Study Notes
Anatomical Position
- Describes a standardized position of the body for anatomical reference.
- Body stands upright, facing forward, with arms at sides, palms facing forward, and feet together.
Planes of the Body
- Median Plane: Divides the body into equal right and left halves.
- Transverse Plane: Divides the body into superior and inferior portions.
- Coronal Plane: Divides the body into anterior and posterior portions.
Superficial Fascia
- A layer of connective tissue located just beneath the skin.
- Contains fatty tissue (adipose) except in specific areas like eyelids and the auricle of the ear.
- Facilitates skin movement.
Deep Fascia
- Dense fibrous sheet located beneath the superficial fascia.
- Devoid of fat, inelastic, and tough.
- Invests the body and provides support and structure.
Skin (Integument)
- Body's largest organ, approximately 2 square meters in an average adult.
- Weighs around 9-11 pounds.
- Continuously replaced, with new skin cells produced every 25-45 days.
- Integumentary system includes skin and its appendages: hair, nails, and skin glands.
Skin Layers
- Epidermis: Outermost layer of skin, consists of stratified squamous epithelium.
- Dermis: Inner layer of skin, composed of dense connective tissue.
Melanin Production
- All races have the same number of melanocytes (cells that produce melanin).
- Darker skinned individuals have higher melanin production.
- Albinism occurs due to a lack of melanin due to mutant melanin genes.
