Study Notes

Muscle Groups and Their Locations

Sternocleidomastoid: Positioned at the front of the neck, aids in neck rotation and flexion.
Platysma: Located in the neck region, involved in facial expressions.
Pectoralis Major: Found beneath the breast area, plays a key role in shoulder movement.
Rectus Abdominis: Located under the ribs, essential for trunk flexion and posture.
External Oblique: Located on the sides of the abdomen, important for trunk rotation and lateral flexion.

Upper Back and Shoulder Muscles

Trapezius: Covers the upper back and neck area, supports shoulder movement and arm elevation.
Latissimus Dorsi: Situated on the sides of the upper back, important for arm adduction and extension.
Erector Spinae: A deep muscle in the back, crucial for maintaining spinal posture.

Arm Muscles

Deltoid: The primary shoulder muscle, responsible for arm abduction and flexion.
Biceps Brachii: Located in the upper arm, works on elbow flexion and forearm supination.
Brachialis: Smaller muscle beneath the biceps, assists in elbow flexion.
Triceps Brachii: Found on the back of the upper arm, responsible for extending the elbow.

Thigh Muscles

Illopsoas: Upper thigh muscle near the pelvis, key for hip flexion.
Adductor Muscles: Situated towards the back of the upper thigh, important for leg adduction.
Sartorius: Runs from the hip to the inner thigh, aids in knee flexion and hip rotation.
Rectus Femoris: Part of the quadriceps group, located in the upper thigh near the knee.
Vastus Lateralis: Another quadricep muscle, found outside the knee area.

Leg Muscles

Tibialis Anterior: Muscle in the front of the lower leg, crucial for ankle dorsiflexion.
Fibularis Longus: Located on the inside of the lower leg, aids in foot eversion.

Lower Arm Muscles

Flexor Carpi Ulnaris: A thick muscle on the lower arm, involved in wrist flexion.
Extensor Digitorum: Anterior muscle on the lower arm, responsible for finger extension.
Extensor Carpi Ulnaris: Located on the lateral side of the lower arm, involved in wrist extension.
Extensor Carpi Radialis: Found on the medial side of the lower arm, contributes to wrist stability.

Gluteal and Calf Muscles

Gluteus Maximus: Primary muscle of the buttocks, essential for hip extension.
Gluteus Medius: Smaller muscle located above the gluteus maximus, vital for hip stability.
Hamstring: Refers to the group of muscles at the back of the thigh, important for knee flexion and hip extension.
Gastrocnemius: Major calf muscle, involved in plantar flexion of the foot.
Soleus: Located beneath the gastrocnemius, assists in maintaining posture and movement of the ankle.
