Which muscle is crucial for neck movement and posture?

Sternocleidomastoid

Which muscle is involved in breathing by moving the ribs?

Intercostal muscles

Which muscle is responsible for chewing movements like clenching the jaw?

Masseter

What muscles are important for shoulder movement and stability?

Study Notes

Introduction to the muscles of the body covering muscles of the head, neck, trunk, back, and limbs
Focus on skeletal muscles that are under voluntary control, excluding smooth muscle and cardiac muscle
Muscles of the face include muscles of facial expression and muscles of mastication like the masseter
Muscles of the neck include sternocleidomastoid and trapezius, important for neck movement and posture
Muscles of the back include multiple layers of muscles involved in supporting the spine and moving the ribs for breathing
Core muscles in the trunk include intercostal muscles, diaphragm, and abdominal muscles for breathing and core stability
Upper limb muscles include muscles like deltoid, latissimus dorsi, pectoralis major, trapezius, and rotator cuff muscles for shoulder movement and stability
Lower limb muscles are large and support body weight during activities like walking, standing, and running
Hip joint muscles include quadriceps femoris group for knee extension and hip flexion, and adductor muscles for hip adduction
Hamstring muscles in the posterior compartment cross the hip and knee joints for hip extension and knee flexion
Muscles in the gluteal region like gluteus maximus are powerful hip extensors, important for standing up from a seated position- The posterior compartment of the lower leg contains muscles that help with plantar flexion and inversion of the foot.
The anterior compartment of the lower leg contains muscles that assist with dorsiflexion and extension of the toes.
The lateral compartment of the lower leg houses the fibularis muscles which aid in eversion of the foot.
These muscles work together to stabilize the body, especially when standing on one foot.
In the foot, there are numerous small muscles that contribute to fine movements of the toes, similar to the hand.
