Study Notes
The Skeletal System
- The skeletal system consists of bones that provide structure, support, and protection for the body.
- It enables movement by serving as levers worked on by muscles.
- Critical functions include the production of blood cells (hematopoiesis) and storage of minerals like calcium.
The Muscular System
- The muscular system is composed of muscles allowing for movement, stability, and heat production in the body.
Major Muscles to Label
- Biceps: Located in the upper arm, facilitates elbow flexion.
- Triceps: Opposite the biceps, responsible for elbow extension.
- Deltoid: Shoulder muscle, crucial for arm rotation and lifting.
- Pectoralis: Chest muscle, involved in arm movement and pushing actions.
- Rectus Abdominis: Central abdominal muscle aiding in trunk flexion.
- Obliques: Side abdominal muscles, assist in twisting and bending.
- Quadriceps: Front thigh muscle group, extends the knee.
- Vastus Lateralis: Part of quadriceps, located on the outer thigh.
- Vastus Medialis: Part of quadriceps, located on the inner thigh.
- Sartorius: Long, thin muscle running across the thigh, aids hip and knee flexion.
- Adductor: Muscle group on the inner thigh, responsible for thigh adduction.
- Trapezius: Upper back muscle, responsible for shoulder elevation and neck movement.
- Tibialis Anterior: Muscle located in the front of the lower leg, involved in ankle dorsiflexion.
- Soleus: Calf muscle, important for standing and walking.
- Frontalis: Forehead muscle, involved in raising eyebrows and forehead movement.
Physiology Terminology
- Flexion: Action decreasing the angle between two body parts.
- Extension: Action increasing the angle between two body parts.
- Hyperextension: When a joint moves beyond its normal range of motion.
- Abduction: Movement of a body part away from the midline.
- Adduction: Movement of a body part toward the midline.
- Inversion: Inward rolling of the foot.
- Eversion: Outward rolling of the foot.
- External Rotation: Movement that rotates the leg at the hip, turning the foot and knee outward.
- Internal Rotation: Movement that rotates the leg at the hip, turning the foot and knee inward.
