Additional Muscle Groups and Bone Structure
This page continues the GCSE PE muscle diagram from the previous page, focusing on the posterior view of the human body. It provides a clear illustration of additional muscle groups and their relation to the skeletal structure.
The muscles highlighted in this diagram include:
- Deltoid
- Triceps
- Latissimus dorsi
- Hamstring
- Gastrocnemius (calf)
Highlight: The diagram clearly shows the extensive coverage of the latissimus dorsi, demonstrating its importance in upper body movements.
Vocabulary: Posterior - Relating to or situated at the back of something, in this case, the back of the human body.
The illustration also emphasizes the relationship between muscles and bones, providing a comprehensive view of the musculoskeletal system from the back.
Example: The triceps muscle is shown extending along the back of the upper arm, illustrating its role in arm extension movements.
This diagram is particularly useful for understanding the sporting example of latissimus dorsi usage, as it clearly shows the muscle's extensive coverage of the back, indicating its importance in pulling movements such as in swimming or rowing.
The inclusion of both muscle and bone structures in this diagram helps students understand how these systems work together to produce movement, which is crucial knowledge for GCSE PE muscles study.
Definition: Gastrocnemius - The prominent muscle of the calf, responsible for plantar flexion of the foot.
This visual representation, combined with the previous page's diagram, provides a complete 360-degree view of the major muscle groups studied in GCSE PE, making it an invaluable resource for students.
