Anatomy and Physiology Chapter 1

Directions, Planes, Cavities, Homeostasis

Anatomy- studies the form and structure of the body.

Physiology- examines how the body functions

Structure and function are inseparable

Together, they provide the basis for understanding health and human

performance

Human Anatomy Foundation

Anatomic Position- upright stance, feet parallel and flat on floor, upper limbs at sides

of body, palms face anteriorly (towards the front), head is level, eyes look forward

Prone- body lying facedown

Supine- body lying faceup (supine-spine, lying on spine)

Regional Names- Cephalic (head), Cervical (neck), Trunk, Upper limb, lower limb

Anatomic Directions

Anterior/Ventral- closer to the front

Posterior/Dorsal- closer to the back

Proximal- closer to attachment

Distal- farther from attachment

Superior/Cranial/Cephalic- closer to head

Inferior/Caudal- farther from head

Medial- closer to midline

Lateral- farther from midline

Deep- deeper than superficial

Superficial- closer to surface

Intermediate- in between

Ipsilateral- two parts on same side

Contralateral- two parts on opposite sides

Sections and planes

Coronal plane/Frontal plane- divide body into front and back

Transverse plane- divide body into top and bottom

Midsagittal plane- divide body into equal left and right halves

Sagittal plane- divide body into unequal left and right structures

Oblique plane- pass through structures at an angle

Parasagittal- unequal left and right sides
