Study Notes
Muscle Identification
- Rectus Femoris: Located in the middle of the thigh; part of the quadriceps muscle group.
- Sartorius: Longest muscle in the body; runs diagonally from the hip to the knee.
- Pectoralis Major: Large chest muscle responsible for arm movement; fan-shaped.
- Rectus Abdominis: Known as the "abs," this muscle runs vertically along the front of the abdomen.
- Adductor Longus: Located in the inner thigh; involved in hip adduction.
- Hamstrings - Biceps Femoris: One of three muscles located at the back of the thigh; aids in knee flexion.
- Internal Abdominal Oblique: Located beneath the external oblique; supports trunk, aids in rotation and lateral movement.
- Hamstrings - Semimembranosus: Another muscle in the back of the thigh, it works to flex the knee.
- Serratus Anterior: Located on the side of the chest; important for shoulder movement and stability.
- Latissimus Dorsi: Large back muscle; responsible for arm movement and swimming actions.
- External Abdominal Oblique: Outermost muscle layer of the abdomen; aids in rotation and side bending.
- Trapezius: Upper back muscle; supports the shoulder and neck movement.
- Infraspinatus: Part of the rotator cuff; important for shoulder stability and rotation.
- Supraspinatus: Also part of the rotator cuff; initiates arm abduction.
- Sternocleidomastoid: Neck muscle that assists in rotation and flexion of the head.
- Gluteus Maximus: Major muscle of the buttocks; involved in hip extension.
- Gluteus Medius: Located on the outer surface of the pelvis; important for hip stabilization.
- Gastrocnemius: Major calf muscle involved in walking, running, and jumping.
- Soleus: Positioned beneath the gastrocnemius; also aids in walking and standing.
- Masseter: Key muscle for jaw movement; plays a critical role in chewing.
- Frontalis: Forehead muscle; responsible for raising eyebrows and wrinkling the forehead.
- Temporalis: Muscle on the side of the head; helps in closing the jaw.
- Occipitalis: Located at the back of the head; assists in moving the scalp.
- Orbicularis Oris: Muscle around the mouth; enables lip movement and closure.
- Orbicularis Oculi: Muscle surrounding the eye; responsible for blinking and closing the eyelids.
- Zygomaticus: Muscle that raises the corners of the mouth; involved in smiling.
- Deltoid: Shoulder muscle that allows for a range of arm movements.
- Biceps Brachii: Front muscle of the upper arm; primarily engaged in elbow flexion.
- Triceps Brachii: Muscle at the back of the upper arm; responsible for elbow extension.
- Buccinator: Compresses the cheeks; helps in mastication and blowing.
- Brachialis: Located beneath the biceps; plays a key role in elbow flexion.
- Brachioradialis: Forearm muscle; assists with elbow flexion.
- Flexor Carpi Ulnaris: Wrist flexor on the ulnar side; allows for movement and stabilization.
- Flexor Carpi Radialis: Flexes and abducts the wrist; located on the radial side.
- Flexor Digitorum: Allows for flexion of the fingers; vital for gripping.
- Extensor Digitorum: Extends fingers and the wrist; located on the posterior side of the forearm.
- Extensor Carpi Radialis: Extends and abducts the wrist; located along the radial side.
- Extensor Carpi Ulnaris: Extends and adducts the wrist; found on the ulnar side.
- Iliopsoas: Major hip flexor composed of psoas major and iliacus muscles.
- Tibialis Anterior: Located in the front of the shin; responsible for dorsiflexion of the foot.
- Extensor Digitorum Longus: Extends the toes; important for walking.
- Fibularis Longus: Lateral side of the lower leg; helps with foot eversion.
- Soleus: Positioned under the gastrocnemius; works with it for plantar flexion.
- Vastus Medialis: Part of the quadriceps; located on the inner thigh; aids in knee extension.
- Vastus Lateralis: Positioned on the outer thigh; another component of the quadriceps.
- Vastus Intermedialis: Situated beneath the rectus femoris; plays a role in knee extension.
