Study Notes
Muscles
- A muscle is fibrous tissue attached to bone that enables movement.
- Muscles assist with balance, movement, and strength.
- Muscle contraction shortens muscle fibers, while elongation allows muscles to relax and lengthen.
Major Muscle Groups
- Pectoralis Major: Large, fan-shaped muscle covering the front upper chest, attached to the sternum, clavicle, and humerus. It moves the arm across the body.
- Biceps Brachii: Runs from the shoulder to the elbow, attached to the scapula and humerus. It flexes the arm at the elbow.
- Triceps Brachii: Large, thick muscle on the back of the upper arm, responsible for extending the elbow joint.
- Trapezius: Large, flat, triangular muscle located on the upper back and neck, involved in head, neck, and shoulder movements.
- Deltoid: Triangular muscle of the shoulder, responsible for raising the arm sideways, and twisting the arm.
- Latissimus Dorsi: Large, flat, triangular muscle located in the middle and lower back, involved in shoulder, arm, and trunk movements.
- Rectus Abdominis: Pair of long muscles running vertically along the front of the abdomen, compressing the viscera and tensing the abdominal wall.
- Internal & External Obliques: Muscles located laterally on the abdomen, working together to provide core strength and stability.
Leg Muscles
-
Quadriceps: A group of four muscles located on the front of the thigh:
- Rectus Femoris: Extends the knee and flexes the hip.
- Vastus Lateralis: Extends the knee.
- Vastus Medialis: Extends the knee.
- Vastus Intermedius: Extends the knee.
- Hamstrings: Group of three muscles located on the back of the thigh, responsible for hip extension and knee flexion.
- Gastrocnemius: Prominent muscle located in the calf, responsible for plantar flexing the foot and flexing the knee.
- Soleus: Muscle located beneath the gastrocnemius in the calf, also responsible for plantar flexing the foot.
-
Gluteals: Group of muscles located in the buttocks, responsible for hip extension, hip abduction, and pelvic stability.
- Gluteus Maximus: The largest and most superficial of the gluteal muscles.
- Gluteus Medius: Located beneath the gluteus maximus.
- Gluteus Minimus: Smallest gluteal muscle, located beneath the gluteus medius.
