Cytology

study of body cells and their internal structure.

Andreas Vesalius

wrote and illustrated the first comprehensive textbook of anatomy.

Basic Principles of Cell Theory:

Cells are the structural building blocks of all plants and animals Cells are produced by the divisions of pre-existing cells. Cells are the smallest structural units that perform all vital functions.

urinary system functions

Eliminates waste from the body; regulates water balance of the blood (kidney, ureter, bladder)

Regional anatomy:

Focuses on superficial anatomic markings and internal body structures.

skeletal system

Protects and supports body organs and provides a framework the muscles use to support movement. Made up of bones and joints

cardiovascular system function

Pump, distribute blood which carries oxygen, nutrients and wastes to and from the cells. (blood vessels, heart)

endocrine system function

Secretes hormones that regulate processes such as growth, reproduction, and metabolism by body cells (glands, thymus, kidneys, pancreas...)

Embryology

Studies developmental changes from conception to birth.

Anatomical position:

The erect position of the body with the face directed forward, the arms at the side, and the palms facing forward, used as a reference the relation of body parts to one another.

sacral

area between hips

The anatomical term for cheek is ______, whereas the anatomical term for chin is ______.

buccal, mental

The correct anatomical term for head is ______.

chemical level, cellular level, tissue level, organ level, organ system level, organismal level

The body's ability to maintain an average temperature of about 37°C regardless of the outside temperature is called

homeostasis

transverse plane

horizontal division of the body into upper and lower portions

popliteal

Which of the following statements correctly apply to homeostasis as a physiologic process?

-Negative feedback typically keeps these processes in check. -The control center is generally the nervous system or endocrine system. -When homeostasis fails disease or even death occurs. -These processes are dynamic.

respiratory system function

Bring oxygen to and eliminates carbon dioxide from the blood. (nasal cavity, nose, lungs, bronchi, trachea, larynx, pharynx)

True or false: Most processes in the body are controlled by negative feedback.

true

vertebral

Mammary is to ______ as brachial is to arm.

breast

thoracic cavity

contains heart and lungs

vertebral cavity

contains the spinal cord

coronal plane

divides body into front and back

Pathophysiology:

focuses on the function of a body system during disease or injury to the system.

Pes refers to the ______.

foot

Frontal refers to the ______.

forehead

The anatomical term describing the groin is

inguinal region

Reproductive physiology

investigates functioning of resporductive hormones and the reproductive cycle.

Cardiovascular physiology:

examines functioning of the heart, blood vessels, and blood

Pathologic anatomy

examines macroscopic and microscopic anatomic changes resulting from disease.

Microscopic anatomy

examines structures that cannot be observed by unaided eye -specimen examined under microscope.

Respiratory physiology

explores the functioning of respiratory organs

True or false: Because the end result of a positive feedback mechanism is to increase the activity, positive feedback mechanisms are much more common than negative feedback mechanisms.

false
