Cards

Term
Simple Squamous Epithelium
Definition

Function: Allows passages of materials by diffusion and filtration in sites where protection is not important; secretes lubricating sustances in serosae

 

Location: Kidney glomerull; air sacs of lungs; lining of hearts, blood vessels, and lymphatic vessels; lining of ventral body cavity (serosae)

Term
Simple Cubidol Epithelium
Definition

Function: Secretion and absorption

 

Location: Kidney tubules; ducts and secretory portions of small glands; ovary surface

Term
Simple Columnar Epithelium
Definition

Function: Absorption; secretion of mucus, enzymes, and other substances; ciliated type propers mucus (or reprodcutive cells) by ciliary action.

 

Location: Nonciliated type lines most of the digestive tract (stomach to anal canal), gallbladder, and excretory ducts of some glands, ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus

Term
Pseudostratified Columnar Epithelium
Definition

Function: Secretion, particularly of mucus; propulsion of mucus by ciliary action

 

Location: Nonciliated type in male's sperm-carrying ducts and ducts of large glands; ciliated variety lines the trachea, most of the upper respiratory tract.

Term
Stratified Squamous Epithelium
Definition

Function: Protects underlying tissues in areas subjected to abrasion

 

Location: Nonkerantinized type fors the most linings of the esophagus, mouth, and vagina; keratinized variety forms the epidermis of the skin, a dry membrane

Term
Stratified Cubidol Epithelium
Definition

Function: Protection

 

Location: Largest ducts of sweat glands, mammary glands, and salviary glands

Term
Transitional Epithelium
Definition

Function: Stretches readily and permits distension of urinary organ by contained urine.

 

Location: Lines the ureters, urinary bladder, and parts of the urethra

Term
Areolar
Definition

Function: Wraps and cushions organs; its macrophages phagocytize bacteria; plays important role in inflammation; holds and conveys tissue fluids

 

Location: Widely distributed under epithelia of body, e.g. forms lamina propria of mucous membranes; packages organs; surround capilaries

Term
Adipose
Definition

Function: Provides reserve fuel; insulates against heat loss; supports and protects organs

 

Location: Under skin; around kidneys and eyeballs; within abdomen; in breasts.

Term
Dense Regular
Definition

Function: Attaches muscles to bones or to mucles; attaches bone to bones; withstands great tensile stress when pulling force is applied in one direction

 

Location: Tendons, most ligament, apneuroses.

Term
Hyaline
Definition

Function: Supports and reinforces; has resilent cushioning properties; resists compressive stress.

 

Locaiton: Forms most of the embryonic skeleton; covers the end of long bones in joint cavaties; forms costal cartilage of the ribs; cartilage of the nose, trachea, and larynx

Term
Osseous Tissue
Definition
Function: Bone supports and protects (by enclosing); provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside bones is the site for blood cell formation (hematopoiesis)
Term
Blood
Definition

Function: Transport of respiratory gasses, nutrients, wastes, and other substances

 

Location: Contained within blood vessels

Term
Nervous Tissue
Definition

Function: Transmit electircal signals from sensory receptors and to effectors (muscles&glands) which control their activity.

 

Location: Brain, spinal cord, and nerves

Term
Skeletal Muscle
Definition

Function: Voluntary movement; locomotion; manipulation of the enviornment; facial expression; voluntary control

 

Location: In skeletal muscles attached to bones or occasionally to skin

Term
Cardiac Muscle
Definition
Function: As it contracts, it propels blood into the circulation; involuntary control
Term
Smooth Muscle
Definition

Function: Propels substances or onjects (foodstuffs, urine, a baby) along internal passageways; involuntary control

 

Location: Mostly in the walls of hollow organs
