Cartilage and Bone Structure
Think of cartilage as your body's built-in shock absorber - it's flexible, bounces back after bending, and doesn't have its own blood supply (so it relies on slow diffusion for nutrients). The cells inside cartilage are called chondrocytes, and they're surrounded by a protein called chondrin.
There are three main types you need to know. Hyaline cartilage is the weakest and becomes bone as you develop. Yellow elastic cartilage sits in the middle for flexibility. White fibrous cartilage is the strongest because it's packed with organised collagen fibres.
Bone does way more than just hold you up - it protects organs, stores minerals like calcium, and even makes your blood cells in the bone marrow. You've got two types: compact bone (solid and strong) and spongy bone (lighter with spaces).
Key insight: Osteoblasts build bone up whilst osteoclasts break it down - think of them as your body's construction and demolition crews working 24/7.
Bone Formation and Muscle Types
Bones form in two ways: cartilage bones develop when osteoblasts build layers around existing cartilage whilst osteoclasts break the cartilage down, and membrane bones form directly from embryonic tissue.
Your body has three types of muscle tissue. Skeletal muscle is what you control voluntarily and has those distinctive stripes (striations) under a microscope. This muscle is made up of myofibrils containing the proteins actin, myosin, troponin, and tropomyosin arranged in repeating units called sarcomeres.
Each sarcomere has specific bands: the A band (dark, thick myosin), I band (light, thin actin), Z lines (marking sarcomere boundaries), and the M line (centre of thick filaments). Skeletal muscle cells are unusual because they have multiple nuclei - this happens when several cells fuse together during development.
Remember: The arrangement of these protein filaments creates the striped appearance that gives skeletal muscle its name.
Sliding Filament Theory
The T-system is crucial for muscle contraction - it's basically infoldings of the muscle membrane that carry nerve impulses deep into the muscle fibre, ensuring all parts contract simultaneously.
Muscle contraction works through the sliding filament theory. Thin filaments contain three proteins: G-actin (globular proteins) that join to form F-actin chains, tropomyosin , and troponin (globular protein at intervals). Thick filaments are made entirely of myosin molecules with globular heads that have ATPase activity.
During contraction, sarcomeres shorten but the A band stays the same length because it's defined by the myosin filaments. The I band and H zone both get shorter as the filaments slide past each other.
Quick tip: Think of it like a telescope closing - the parts slide past each other but don't actually change length themselves.
Muscle Contraction Process
Excitation-contraction coupling is the process that turns a nerve signal into actual muscle movement. When a nerve impulse hits the muscle, it travels along the sarcolemma and T-tubules, causing calcium channels to open in the sarcoplasmic reticulum.
The released calcium ions bind to troponin, which changes shape and moves tropomyosin, exposing binding sites on actin. Myosin heads then form cross-bridges with actin, and when ADP and phosphate are released, the myosin head changes angle, pulling actin past myosin.
ATP then binds to the myosin head, breaking the cross-bridge, and gets hydrolysed to extend the head again. This cycle repeats until calcium is pumped back into the sarcoplasmic reticulum and contraction stops.
Key fact: No ATP means no muscle relaxation - this is why rigor mortis happens after death when ATP runs out.
Fast vs Slow Twitch Muscle Fibres
Your muscles contain two main fibre types with completely different jobs. Slow twitch fibres are your endurance champions - they contract slowly but can keep going for ages without getting tired. They're packed with mitochondria for aerobic respiration and have loads of blood vessels to deliver oxygen.
Fast twitch fibres are built for quick, powerful movements like jumping or sprinting. They contract rapidly but fatigue quickly because they rely mainly on anaerobic respiration. They have fewer mitochondria but more myofibrils for strength.
Muscle fatigue happens for two main reasons: neural fatigue (nerves can't maintain the signal) and metabolic fatigue (lack of glucose or buildup of lactate). When lactate accumulates, it lowers pH and makes proteins less sensitive to calcium, reducing contraction ability.
Real-world example: Chicken drumsticks are dark (slow twitch for walking) whilst breast meat is light (fast twitch for quick flight bursts).
Skeletal Structure and Fractures
Your skeleton divides into two main parts: the axial skeleton (vertebral column, sternum, ribcage) and appendicular skeleton (limbs and girdles). This framework provides support, protection, and attachment points for muscles.
Fractures occur when force exceeds bone strength. Traumatic fractures result from accidents, whilst pathological fractures happen due to medical conditions. The main types include greenstick (bent), linear (parallel to bone), transverse (right angle), oblique (angled), and comminuted (multiple fragments).
Treatment involves pain management , immobilisation with casts, and sometimes surgery with screws or plates. Weight-bearing actually encourages healing by stimulating osteoblasts.
Important distinction: Closed fractures keep skin intact, whilst open fractures break through the skin with high infection risk.
Vertebral Column Structure
Your vertebral column is brilliantly designed as flexible support that protects your spinal cord whilst allowing movement. Each vertebra has a weight-bearing body (spongy bone), an arch protecting the spinal cord, and processes for muscle attachment.
The top two cervical vertebrae are special: C1 (atlas) lets your head nod, whilst C2 (axis) has a peg that allows head rotation. Thoracic vertebrae are proportionally wider and articulate with ribs, whilst lumbar vertebrae are the largest because they bear the most weight.
Different vertebrae shapes correlate perfectly with their functions - cervical for mobility, thoracic for rib attachment, and lumbar for heavy-duty weight bearing.
Memory aid: Think atlas holds up the world (your head) and axis allows rotation around its peg.
Posture, Joints, and Skeletal Functions
Postural deformities include scoliosis , flat foot (lack of arching causing overpronation), and knock knees (feet don't meet when knees touch). These can cause pain and stress on muscles and ligaments but often have effective treatments.
Your skeleton serves multiple functions: structural support, muscle attachment points, organ protection, red blood cell production in bone marrow, and calcium storage for maintaining blood calcium levels.
Joints classify as immovable or movable (synovial). Gliding joints allow multi-directional movement, hinge joints work in one plane, and ball-and-socket joints allow movement in multiple planes.
Clinical note: Many postural problems in children resolve naturally, but severe cases may need bracing or surgery.
Joints as Levers and Movement
Joints work as levers with three components: fulcrum (pivot point), effort (force causing movement), and load (what's being moved). There are three classes based on the arrangement of these components.
First-order levers have the fulcrum in the middle (like your neck balancing your skull). Second-order levers have the load in the middle (standing on toes). Third-order levers have the effort in the middle (bicep lifting your hand).
At equilibrium, levers follow the formula: F₁ × d₁ = F₂ × d₂, where F represents forces and d represents distances from the fulcrum.
Practical application: Understanding lever mechanics helps explain why some movements feel easier or harder depending on angles and positions.
Synovial Joints and Muscle Pairs
Synovial joints are your movable joints with bone ends covered in hyaline cartilage and a cavity filled with synovial fluid. This fluid lubricates, absorbs shock, and nourishes cartilage cells through diffusion.
Antagonistic muscles work in pairs because muscles can only pull, not push. When your bicep contracts to bend your elbow, your tricep must relax. To straighten your elbow, the tricep contracts whilst the bicep relaxes.
Tendons connect muscle to bone using densely packed parallel collagen fibres. They're inelastic (don't stretch) but can store energy and remodel themselves with use. Without regular use, tendons lose diameter and strength.
Fascinating fact: In microgravity, tendons lose their stiffness because they're not experiencing normal loading forces.
