To answer this question in an examination, you can provide a brief overview of the functions of skeletal muscles. Here is a sample answer:
Skeletal muscles play a crucial role in the movement and support of the body. Some of the key functions of skeletal muscles include:
1. Movement: Skeletal muscles are responsible for producing movement by contracting and relaxing in response to signals from the nervous system. This allows us to walk, run, jump, and perform various other physical activities.
2. Posture and support: Skeletal muscles help maintain posture and provide support to the body. They work in coordination with the bones and joints to keep the body in an upright position and prevent it from collapsing.
3. Protection: Skeletal muscles protect internal organs and structures by surrounding and enclosing them. For example, the muscles of the abdominal wall protect the organs in the abdominal cavity.
4. Heat production: Skeletal muscles generate heat as a byproduct of their contraction. This helps regulate body temperature and keep the body warm in cold environments.
Overall, skeletal muscles are essential for the functioning of the musculoskeletal system and play a vital role in maintaining overall health and well-being.

Outline of Skeletal Muscle Functions:
1. Movement and Locomotion:
- Skeletal muscles contract to move bones and joints, enabling various movements such as walking, running, jumping, and reaching.
- They work in pairs: prime movers (agonists) and antagonists (opposing muscles) to perform coordinated movements.
2. Posture and Stability:
- Muscles maintain posture by supporting the joints and resisting gravity.
- They stabilize joints, particularly during static positions.
3. Protection:
- Skeletal muscles protect vital organs such as the heart, lungs, and abdomen.
- They form a thick muscular layer around these organs to cushion them against external impacts.
4. Heat Generation:
- Muscle contractions generate heat as a byproduct.
- This heat helps maintain body temperature, especially in cold environments.
5. Metabolic Control:
- Skeletal muscles are involved in glucose metabolism.
- Insulin-stimulated glucose uptake during exercise is facilitated by the presence of glucose transporters in muscle cells.
6. Storage:
- Skeletal muscles store energy in the form of glycogen, which is broken down into glucose during exercise.
7. Electrical Activity:
- Muscle fibers contain excitable membranes and can generate electrical signals.
- These signals facilitate communication between muscle fibers and allow coordinated contractions.
8. Sensation:
- Specialized sensory neurons within skeletal muscles provide proprioception, which informs the body about the position and movement of joints.
