Nervous System Overview
Your nervous system consists of two main parts working in perfect harmony. The Central Nervous System (CNS) includes your brain and spinal cord, acting as the control centre for your entire body. The Peripheral Nervous System (PNS) connects your CNS to the rest of your body, helping integrate incoming information and determine appropriate responses.
Your body has two types of nerves with different jobs. Sensory nerves (afferent) carry information from your body's sensory receptors to your CNS, telling you what's happening in your environment. Motor nerves (efferent) carry commands from your CNS to muscles or other structures that need to respond.
The nervous system contains two primary cell types. Neurons are specialized nerve cells that receive and transmit stimuli, consisting of three important parts: the cell body (contains the nucleus), dendrites (receive input), and axons (transfer impulses to other cells). Groups of neuron cells clustered together form ganglia.
Did you know? Your nervous system is like a complex electrical circuit - neurons can transmit signals at speeds up to 120 metres per second, faster than a Formula 1 racing car!
Brain Structure and Support
Your nervous system contains billions of glial cells that support and protect neurons. These cells, collectively called neuroglia, actually outnumber neurons and play crucial roles in maintaining brain health.
If you were to look at brain tissue, you'd notice two distinct areas. White matter consists of myelinated axons (nerve fibres covered in a protective sheath), while grey matter contains neuronal cell bodies and neuroglia. This different colouration helps scientists identify different brain regions.
Your brain is protected by the skull and connects to your spinal cord through the foramen magnum, a large opening at the base of your occipital bone. The brain itself contains approximately 100 billion neurons and has 12 pairs of cranial nerves that emerge from its base.
Fascinating fact: Your spinal cord is shorter than your vertebral column! It typically ends around the second lumbar vertebra (L2), while the protective vertebral canal continues all the way down to your sacrum.
Protective Coverings: The Meninges
Your brain and spinal cord are wrapped in three layers of protective tissue called the meninges. These layers serve as a crucial defence system for your delicate neural tissues. Spinal meninges surround your spinal cord, while cranial meninges protect your brain.
The outermost layer is the dura mater, made of dense, irregular connective tissue that runs from the foramen magnum to the second sacral vertebra. Beneath it lies the arachnoid mater (also called meninx), an avascular middle layer. The innermost layer, the pia mater, makes direct contact with both the brain and spinal cord.
A spinal tap is a procedure where a long needle is inserted into the subarachnoid space (the area between the arachnoid and pia mater). Because your spinal cord ends at L2 but your meninges continue to S2, doctors typically perform spinal taps between vertebrae L3/L4 or L4/L5. This provides safe access without damaging the spinal cord.
Remember this: Spinal taps are performed in the lower back because your spinal cord doesn't extend the entire length of your spine! This clever positioning allows doctors to access the cerebrospinal fluid safely.
Spinal Nerves and the Brain
Spinal nerves are your communication pathways between the spinal cord and specific body regions. Your body has 31 pairs of these nerves: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. They branch out from your spine to innervate different areas.
Since your spinal cord ends around the L2 vertebra but your spine continues lower, the nerve roots for your lumbar, sacral and coccygeal regions must travel downward before exiting the vertebral column. This bundle of nerve roots at the inferior end forms the cauda equina, which resembles a horse's tail.
Your brain serves as the grand organising and processing centre of your nervous system. It manages consciousness, sensation, memory, and coordination by receiving impulses from both the spinal cord and 12 pairs of cranial nerves.
Think about this: Your brain accounts for only 2% of your body weight but uses about 20% of your body's oxygen and energy! This remarkable organ contains more connections than there are stars in our galaxy.
Cerebrum Structure and Function
Your cerebrum is divided by shallow grooves called sulci and deeper indentations called fissures. Each cerebral hemisphere contains over 10 billion neurons and is divided into four main lobes, each with specialised functions.
The frontal lobe serves as the primary motor area, controlling voluntary movements. It also contains Broca's area, which is crucial for speech and speech planning. The other lobes—parietal, temporal, and occipital—manage different sensory processing, memory, and visual information.
Inside your cerebrum are fluid-filled spaces called ventricles. These include two large lateral ventricles, one near the corpus callosum (the bridge connecting your brain's hemispheres), and another in the brain stem. All ventricles contain cerebrospinal fluid (CSF), which cushions and protects your brain.
Cool brain fact: Your cerebellum might be small (just 10% of brain volume), but it contains over 50% of all your brain's neurons! This dense packing helps it coordinate complex movements with incredible precision.
Cerebellum and Brain Stem
The cerebellum is a large mass of grey matter located behind the medulla oblongata. It plays a vital role in coordinating your motor activities like walking by determining which muscles to use and controlling the strength and sequence of your movements. Though smaller than the cerebrum, it's crucial for smooth, coordinated actions.
Your cerebellum consists of two lateral hemispheres separated by a layer of dura mater. These hemispheres communicate with other parts of the central nervous system through three pairs of nerve tracts called cerebellar peduncles.
The brain stem connects your cerebrum to your spinal cord and consists of four parts. The diencephalon includes the thalamus (sensory processing centre) and hypothalamus (regulates hormones, hunger, body temperature). The limbic system manages emotions like fear, anger, pleasure and sorrow, influencing which memories you retain. The midbrain acts as a reflex centre, while the pons serves as a nerve impulse relay station.
Remember this: Your brain stem controls vital functions you never think about! This small but mighty structure keeps you breathing, maintains your heartbeat, and enables reflexes like coughing and sneezing without any conscious effort.
The Medulla Oblongata and Cranial Nerves
The medulla oblongata is the swollen top portion of your spinal cord and forms the lowest part of your brain stem. This critical structure serves as the passageway for signals traveling between your brain and spinal cord, and contains the fourth ventricle filled with cerebrospinal fluid.
Your medulla controls many vital automatic functions including your heartbeat, breathing, sneezing, coughing, vomiting, and swallowing. When these functions permanently cease, it's considered an absolute sign of death (alongside generalised decomposition).
Your brain connects directly to sensory organs and muscles through 12 pairs of cranial nerves. The first two are responsible for special senses: the olfactory nerve (I) handles smell, while the optic nerve (II) manages vision. These nerves emerge directly from your brain rather than your spinal cord.
Try this mnemonic: "Oh Once One Takes The Anatomy Final Very Good Vacation Super Heavenly" can help you remember the order of cranial nerves (Olfactory, Optic, Oculomotor, Trochlear, Trigeminal, Abducens, Facial, Vestibulocochlear, Glossopharyngeal, Vagus, Spinal accessory, Hypoglossal).
Cranial Nerves and Their Functions
Cranial nerves III to XII control various functions throughout your head, face and body. The oculomotor (III), trochlear (IV), and abducens (VI) nerves all control different eye movements, allowing you to look in different directions.
The trigeminal nerve (V) has multiple functions including controlling swallowing and providing sensation to your face and tongue. The facial nerve (VII) manages your facial expressions, while the vestibulocochlear nerve (VIII) is responsible for both hearing and balance.
The glossopharyngeal nerve (IX) primarily serves your tongue, while the vagus nerve (X) has extensive functions including regulating your heart and blood vessels. The spinal accessory nerve (XI) controls various visceral functions, and finally, the hypoglossal nerve (XII) controls tongue movements essential for speech and swallowing.
Fascinating fact: Your vagus nerve (X) is the longest cranial nerve and the main component of your parasympathetic nervous system. It helps you relax after stress and explains why deep breathing can calm you down!
Key Anatomical Terms
Understanding anatomical terminology helps you navigate discussions about the nervous system. Anastomosis refers to a connection between vessels, like the Circle of Willis in your brain. Angiology is the study of the circulatory system, while an aneurysm is a blood-filled saclike dilation in an artery wall that can be dangerous.
Terms related to body regions include cubital (forearm), glossal (tongue), hepatic (liver), and nuchal (nape of the neck). Olecranon refers to your elbow, while olfactory relates to your sense of smell.
Other important terms include aponeurosis (a flat sheet of white fibrous tissue similar to a tendon), deferens (carrying away), and morphology (the study of the shape and structure of living organisms). The term orifice simply means an opening, while palpebrae refers to your eyelids.
Study tip: Learning anatomical terminology is like learning a new language! Break words down into their roots - for example, "glosso-" always relates to the tongue, while "-palpebra" refers to eyelids. This makes memorizing much easier.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
