Study Notes

Major Muscles Study Notes

Deltoid: Responsible for arm abduction; located at the shoulder.
Biceps Brachii: Located on the front side of the upper arm; aids in flexing the elbow.
Flexors: Group of muscles found on the anterior side of the forearm; involved in bending motions.
Trapezius: A prominent muscle in the upper back; assists in shoulder movement and posture.
Pectoralis Major: A large muscle in the chest; crucial for movements involving pushing.
Rectus Abdominis: Known for creating the "six-pack"; important for core stability.
External Obliques: Diagonal muscles on the surface of the abdomen; assist in trunk rotation and lateral flexion.
Rectus Femoris: Central muscle of the quadriceps group; plays a key role in extending the knee and flexing the hip.
Vastus Medialis: Located on the inner thigh; part of the quadriceps, helps stabilize the knee.
Vastus Lateralis: Found on the outer thigh; another component of the quadriceps, essential for knee extension.
Tibialis Anterior: Situated at the front of the lower leg; responsible for dorsiflexion and inversion of the foot.
Latissimus Dorsi: A large muscle in the mid and lower back; aids in adduction, extension, and internal rotation of the shoulder.
Extensors: Muscles located on the posterior side of the forearm; involved in extending the wrist and fingers.
Gluteus Medius: Positioned superiorly in the buttocks; critical for hip stabilization and abduction.
Gluteus Maximus: The largest muscle in the buttocks; primarily responsible for hip extension and outward rotation.
Biceps Femoris: One of the hamstrings located on the posterior thigh; involved in knee flexion and hip extension.
Gastrocnemius: The prominent calf muscle; essential for plantarflexion and contributing to walking and running.
