Anatomy Vocab Unit 1

The scientific disipline that studies the function of body structures.

the study of structure

investigates the structure and relationships of large body parts that are visible to the unaided eye

precise organization of similar cells that perform specialized functions

contain two or more tissue types that work together to perform specific, complex functions

an individual stands upright with feet parallel and flat on the floor. The head is level, and the eyes look forward toward the observer. The arms are at either side of the body with the palms facing forward and the thumbs pointion away from the body.

a plane that is parallel to the midsagittal plane, but either to the left or right of it.

extends through the body or organ vertically and divides the structure into right and left halves.

cuts perpendicularly along the long axis of the body or organ.

a vertical plane that divides the body into anterior and posterior parts.

back

front

toward the midline of the body

away from the midline of the body

closest to point of attachment to trunk

Furthest from point of attachment to trunk

on the outside

on the inside, underneath another structure

movement in an anterior-posterior plane of the body that decreases the angle between articulating bones

occures when the trunk of the body moves in a coronal plane laterally away from the body

The opposite of a flexion, which is movement in an anterior-posterior plane that increases the angle between the articulating bone.

is the extention of a joint beyond 180 degrees

which means to "move away," is a lateral movement of the body part away from the body midline.

which means to "move toward," and is the medial movement of a body part toward the body midline.

the sole of the foot turns medially

the sole of the feet turns to face laterally.

is the medial rotation of the forearm so that the palnm of the hand is directed posteriorly or inferiorly

occures when the forearm rotates laterally so that the palm faces anteriorly or superiorly

occurs when the talocrural (ankle) joint is bent such that the superior surface of the foot and toes moves toward the leg.

movement at the talocrural joint permits extension of the foot so that the toes point inferiorly.

is a sequense of movements in which the proximal end of an appendage remains relatively stationary while the distal end makes a circular motion.

is a superior movement of a part.

is an inferior movement of a body part

(to draw forth) is the anterior movement of a body part from anatomic position

(to draw back) is the posteriorly directed movement of a body part from anatomic position.

At the carpometacarpal joint, the thumb moves toward the palmar tips of the fingers as it crosses the palm of the hand.

is a pivoting motion in which a bone turns on its own longitudinal axis.

the organs in the cavities of the body, especially those in the abdominal cavity.

the thoracic and abdominopelvic cavities are lined with thin serous membranes, which are composed of two layers. A parietal layer and a visceral layer.

between the parietal and visceral layers of the serous membrane is a thin serous cavity that is actually a potential space.

Any of various body fluids resembling serum, especially lymph.

a thin extracellular layer between the epithelium and the underlaying connective tissue.
