    Study Notes

    Anatomy Review

    • This review covers anatomical terminology, position, planes, directional terms, movement terms and the skeletal and muscular systems.

    Terminology

    • Anatomical terminology utilizes specific terms to describe body parts and locations. These terms are crucial for precise communication within the medical and scientific communities.

    Anatomical Position

    • This is a standardized reference position for describing the body's structures. The body is standing upright, facing forward, with arms at the sides, and palms facing forward.

    Body Planes

    • Sagittal Plane: Divides the body into left and right halves. Movements along this plane are forward and backward.
    • Frontal (Coronal) Plane: Divides the body into front (anterior) and back (posterior) halves. Movements along this plane are side-to-side.
    • Transverse Plane: Divides the body into top (superior) and bottom (inferior) halves. Movements along this plane are rotational or horizontal.

    Positional Terms

    • Medial: Towards the midline of the body.
    • Lateral: Away from the midline of the body.
    • Proximal: Closer to the origin or the center of the body part.
    • Distal: Further away from the origin or the center of the body part.
    • Anterior: The front of the body.
    • Posterior: The back of the body.
    • Superior: Upper or above.
    • Inferior: Lower or below.

    Movement Terms

    • Flexion: Decreases the angle between two body parts (e.g., bending the arm).
    • Extension: Increases the angle between two body parts (e.g., straightening the arm).
    • Abduction: Movement away from the midline of the body (e.g., raising the arm laterally).
    • Adduction: Movement towards the midline of the body (e.g., lowering the arm).
    • Dorsiflexion: Movement of the top of the foot upward (e.g., raising the foot).
    • Plantarflexion: Movement of the top of the foot downward (e.g., pointing the toes).
    • Circumduction: Circular movement of a body part (e.g., drawing a cone shape with the arm).

    Body Movements: Other

    • Various body movements exist, including rotation, depression, elevation, eversion, inversion and more. Illustrations provide visual examples.

    Skeletal System

    • The skeletal system includes the bones making up the human skeleton.
    • Diagram: Shows the 23 bones mentioned (skull or cranium, mandible, clavicle, humerus, spine, radius, ulna, pelvis or hip bone, femur, patella, tarsals, tibia, metatarsals, phalanges, scapula, sternum, ribs, sacrum, coccyx, carpals, metacarpals, phalanges, fibula).

    Joint Types

    • Fixed Joints: Bones are connected by fibrous tissue and are not movable, and often change as the brain grows. Examples are sutures in the skull.
    • Semi-Moveable Joints: Bones are connected by cartilage, and allow for slight movement. An example is the pubic symphysis.
    • Synovial Joints: Filled with fluid; they permit significant mobility, and are most numerous and versatile.

    Major Joint Types

    • Fibrous Joints: Dense connective tissue and are immobile.
    • Cartilaginous Joints: Connected by cartilage and exhibit limited movement.
    • Synovial Joints: Filled with synovial fluid and allow for a wide range of movement. Subtypes noted, such as hinge, ball-and-socket, pivot, condyloid, saddle, and gliding.

    Muscular System

    • Includes 37 muscles (mentioned in illustrations).

    Muscle Types

    • Skeletal Muscle: Voluntary muscles attached to bones.
    • Smooth Muscle: Involuntary muscles located in various body parts.
    • Cardiac Muscle: Involuntary muscles that form the heart.

    Adenosine Triphosphate (ATP)

    • ATP is the body's direct energy currency, used for all bodily functions, and involved in muscle contractions.
    • ATP release: When energy is needed, ATP splits off one phosphate, becoming ADP.
    • ATP recharge: When the body gains extra energy, ADP is recharges by adding the third phosphate.

    Muscle Fibre Types

    • Type I (Slow-Twitch Fibers): Ideal for endurance activities. High mitochondrial density, good for sustained activities.
    • Type IIa (Fast-Twitch Oxidative Fibers): Suitable for moderate endurance and power activities.
    • Type IIb/IIx (Fast-Twitch Glycolytic Fibers): Ideal for short, powerful, or explosive movements. Low mitochondrial density, and fast fatigues.
