Anatomy and Physiology Flashcards
What is the integumentary system?
Serves as a barrier to protect the body from the outside world. also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.
How many layers of skin are they and what are they called?
3 layers; Epidermis, Dermis, and Hypodermis
Prone Position
Laying flat with body faced down, with forearm and hand turned palmar side down.
Proximal
Closer to the body or attachment point
Distal
Farther from the body or attachment point
What are contained in the dermis? What is contained in the hypodermis?
The dermis contains nerves, sweat glands, and blood vessels. The hypodermis contain subcutaneous fat
Anterior
Towards the front of the body
Posterior
Towards the back of the body
Medial
Towards the middle of the body (the midline)
Lateral
Towards the outer edge of the body (farther from the midline)
Superior
Towards the crown of the head
Inferior
Farther from the crown of the head
Abduction
Movement of the arm/hand laterally from the body.
Term: cyanotic
Bluish discoloration, especially of skin
Circumduction
Circular rotation of the leg at the hip joint.
Adduction
Movement of the arm/hand medially towards the body.
Flexion vs. Extension
Flexion is Forward
Extension is Backward
Term: urticaria
hives
Term: ecchymosis
discoloration of the skin resulting from bleeding underneath, typically caused by bruising
Inversion vs. Eversion of the Feet
Inversion is Inward (rotate medially)
Eversion is Outward (rotate laterally)
Term: erythema
Redness
Term: Keloid
Irregular fibrous tissue formed at site of a scar or injury
Term: pallor
paleness
Dorsiflexion vs. Plantar Flexion of the Feet
Dorisflexion is rotation at the ankle joint towards the dorsum (top) of the foot.
Plantar Flexion is rotation at the ankle joint towards the plantar (bottom) aspect of the foot.
