Study Notes
Musculoskeletal System
- The main function of the musculoskeletal system is to provide movement, stability, and posture to the body.
Skeletal System
- The skeleton protects vital organs during physical activities.
- Bones serve as attachment points for muscles.
Joints
- Joints enable movement in the musculoskeletal system.
- Hinge joints allow only backward and forward motion, similar to the hinge on a door.
- Condyloid joints enable movement in the wrist.
- Ball-and-socket joints are formed by the rounded head of a long bone fitting into a cup-shaped hole.
- Pivot joints are similar to ball-and-socket joints but the ball rests against the end of a bone, rather than inside a socket.
Muscles
- Skeletal muscles provide stability and posture to the body.
- Skeletal muscles can be contracted or relaxed voluntarily and are under an individual's control.
- Smooth muscles are involuntary and contract and lengthen by themselves.
- Gastrocnemius muscle enables plantar-flexion of the ankle.
- Tibialis anterior muscle enables dorsiflexion of the ankle.
Muscle Movement
- Antagonistic pairs of muscles work together to bend (flex) and straighten (extend) joints.
- Biceps muscle contracts during a bicep curl.
- Quadriceps contracts and hamstring relaxes to extend the knee joint.
- Hamstring muscles primarily work during activities that involve bending the knee, such as running or jumping.
Safety and Protection
- A helmet is needed to safeguard vital organs during high-impact sports, such as football or rugby.
- Ligaments join one bone to another, holding things together and keeping them stable.
