Definition
Study of Tissues
Term
4 Kinds of Tissue
Definition

Epithelial

Connective

Muscle

Nerve

Term
Epithelial Tissue
Definition

Functions in 4 ways

1) protects

2) absorbs

3) secretes (mucus, hormones, and enzymes)

4) excretes waste (ie urea in sweat)

 

 

Term
Basement membrane
Definition
anchor and adhesive for epithelial cells
Term
Epithelial tissue is made of
Definition
cells closely packed together with very little intercellular material
Term
Epithelial tissue is named
Definition
according to its shape, arrangement or function
Term
Squamous epithelial cells
Definition

Classification based on shape

flat cells

serve a protection function (ie lining mouth and skin)

Term
Cuboidal epithelial cells
Definition

Classification based on shape

shaped like cubes

function - protection and secretion

Term
Columnar Epithelial cells
Definition

Classification based on shape

tall and retangular

function - secretion and absorption

Term
Simple epithelium
Definition

classification of arrangement

one cell layer thick

Term
Stratified epithelium
Definition

classification of arrangement

Several layers of cells thick

Term
Pseudostratified epithelium
Definition

classification of arrangement

Looks thick but not

cells extend from basement membrane to outer surface

Term
Transitional Epithelium
Definition

classification of arrangement

several layers of closely packed stretchy cells

when stretched they look flat

when relaxed they look ragged or saw toothed

Term
Mucous membrane
Definition

Classification Based on Function

produces mucous

Protects, absorbs nutrients, secretes enzymes and bile salts

Term
Simple exocrine gland
Definition

Classification Based on Function

sweat and sebaceous glands

single unbranching ducts

Term
Compound exocrine glands
Definition

Classification Based on Function

made of several branching lobules with branching ducts

ie mammary and large salivary

Term
Endocrine glands
Definition

Classification Based on Function

ductless

secrete hormones into bloodstream

Term
Endothelium
Definition

Classification Based on Function

Lines the blood and lymphatic vessels

endothelium of the heart is called the endocardium

Term
Mesothelium
Definition

Classification Based on Function

Serous tissue lines the great cavities

peritoneum lines the abdominal cavity

pericarium covers the heart

Term
Connective tissue
Definition

made of cells with lots of intercellular material

ie matrix

Term
fibers
Definition

tough collagen or flexible elastin

can be embedded into matrix

Term
3 subgroups of connective tissue
Definition
loose, dense, and specialized
Term
3 types of loose connective tissue
Definition

areolar, adipose, and reticular

 

Term
loose connective tissue
Definition
fills space between and penetrates into organs
Term
Areolar Tissue
Definition

most widely distributed loose connective tissue

 

Term
3 types of cells in Areolar Tissue
Definition

fibroblasts (make fibrils for repair)

histiocytes / macrophages (do phagocytosis)

mast cells (produce anticoagulant heparine and histamine - an inflammatory)

Term
Adipose tissue
Definition

loose connective tissue with fat stored in cells

protects and insulates

Term
Reticular tissue
Definition
forms the framework of the liver, spleen, lymph nodes and bone marrow
Term

Dense connective tissue

having regular arrangement of embedded fibers are

 

Definition

tensons, ligaments and aponeuroses

 

Term

Dense connective tissue

having irregular arrangement of embedded fibers are

Definition
muscle sheaths, joint capsules and fascia
Term
chondrocytes
Definition
cells of cartilage
Term
3 types of cartilage tissue
Definition

hyaline

fibrocartilage

elasic

Term
Hyaline cartilage
Definition

found in the coastal cartilages 

  1. attach the ribs to the sternum
  2. in the septum of the nose
  3. in the rings that keep the trachea and bronchi open
Term
Fibrocartilage
Definition

very strong

intervertebraldisks are made of it

Term
Elastic Cartilage
Definition

easily stretched and flexible

found in ears, eppiglottis and auditory tubes

Term
2 types of bone tissue
Definition

compact / dense

cancellous / spongy

Term
osteocytes
Definition
bone cells embedded in a matrix of calcium and phosporous (mineral salts = hardness of bone)
Term
Dentin
Definition

teeth material

crown of teeth covered with enamel

Term
blood
Definition

liquid portion / plasma and blood cells

 

Term
blood cells
Definition
formed in red bone marrow / hematopoietic tissue
Term
lymphoid tissue
Definition

makes up lymph glands, thymus, spleen, tonsils and adenoids.

produces plasma cells / B lymphocytes producing antibodies

Term

Reticuloendothelial System

RE system

Definition

involved in phagocytosis in connective tissue

RE cells line the spleen and bone marrow

Term
Macrophage
Definition
phagocytic cell of the RE system
Term
Microglia
Definition
cells that do phagocytosis in the nervous system
Term
synovial membranes
Definition

line joints and bursae

produce synovial fluid - lubricant for joints and nourishment for cartilage

Term
Connective tissue functions
Definition

supports

provides nourishments

transports blood enzymes and hormones

connects tissues

provices movement via bones

insulates and maintains temp

protects vital organs

provides storage areas - calcium, phosphorous, fat

attaches / separates other tissues of body

Term
3 types of muscle tissue
Definition

smooth

striated / skeletal

cardiac

Term
muscle cells under contraction
Definition

interaction of two proteins, actin and myosin

shortening of length

pulls on bones thru tendons and brings movement

Term
smooth muscle cells
Definition

long, unicellular, nonstiated

involuntary with 2 l ayers

found in digestive tract, arteries veins

Term
striated / skeletal muscule cells
Definition

long, multinucleated and striated

voluntary pull on bone = movement

Term
cardiac muscle
Definition

only in heart

striated,  uninucleated, cylindrical in shape

responsible for pumping blood thru heart

Term
nervous tissue
Definition

2 layers of cells

neurons = conducting cells

neuroglia = supporting & protecting cells

Term
neuron
Definition
cell body w nucleus, extensions of the cell body - dendrites, and a long axon with axon endings
