Sample Solution
Skeletal Muscles and Joints: Anatomy and Physiology
Anatomy:
- Skeletal muscles: Striated muscles attached to bones by tendons. They contract and relax to produce movement.
- Joints: Where two or more bones meet, allowing movement. Different types of joints exist, offering varying degrees of movement (e.g., hinged, ball-and-socket).
Key Points:
- Skeletal muscles work in pairs (agonist and antagonist) to create movement.
- Joints are classified by their structure and movement range.
- Cartilage provides cushioning and support within joints.
Physiology:
- Muscle contraction: Muscles shorten due to the interaction of thin (actin) and thick (myosin) filaments.
- Nervous system control: The nervous system sends signals to muscles, triggering contraction or relaxation.
- Skeletal muscle fatigue: Prolonged muscle activity depletes energy stores, leading to fatigue and decreased muscle power.
Key Points:
- Muscle contraction is a complex process involving energy release and protein interactions.
- The nervous system plays a crucial role in coordinating muscle movement.
- Understanding muscle fatigue is important for various physical activities.
