Cards

Term
Homeostasis
Definition

The steady state within an organism for maintaining health (normal hydration and composition of body fluids, respiratory and heart rate, temperature)

Term
Cytology
Definition
The study of the structure and function of the cell
Term

Tissue

Definition
A group of cells that work together to perform a specific function
Term
Histology
Definition
The microscopic study of the structure and function of tissue
Term
Tissue Organs
Definition

Groups of tissues that cooperate to perform a specific systemic function

Ex: Stomach, which consists of epithelia, muscle, nervous and connective tissue

Term
Gross Anatomy
Definition
The study of the structure and function of organs with the naked eye
Term
Organ System
Definition
Multiple organs functioning together to complete a task
Term
Histological Stains
Definition

Specialized dyes to recognize various cellular organelles

H&E

Definition

membrane protein

 

binds to and moves particles through

the membrane

 

(transport small substances such as molecules and ions)

Term

Receptor

Definition

carbohydrate component

 

activate or inhibit cell function

Term
Surface Markers
Definition

Carbohydrate (glyco-)

 

Identify the cell as "self"

Term
Endocytosis
Definition

Within

 

2 methods, each where a vesicle created is then pinched off (a phagosome) within the cell and later fused with a lysosome for intracellular digestion

Term
Pinocytosis
Definition

Method of endocytosis

 

Cell drinking

 

Invagination of the cell membrate to entrap extracellular FLUID of anything in solution

Term
Exocytosis
Definition

Out of cell

 

2 methods

bulk release of materials

Term
Excretion
Definition

Method of exocytosis

 

Loss of waste products from the cell

Term
