COLLEGE A & P

tissue

A group of similar cells that perform the same function.

innervated

supplied by nerve fibers

columnar

column shaped

endocrine

secreting internally

exocrine

secreting externally

elastin

protein base similar to collagen that forms elastic tissue

mast cell

Cells that release chemicals (such as histamine) that promote inflammation.

loose connective tissue

areolar, adipose, reticular

dense regular connective tissue

Function: attaches muscles to bones or to muscles; attaches bones to bones; withstands great tensile stress when pulling force is applied in one direction Location: tendons, most ligaments, aponeuroses

fibrocartilage

cartilage that contains fibrous bundles of collagen, such as that of the intervertebral disks in the spinal cord.

skeletal muscle tissue

Voluntary muscle pulls on bones and causes body movements.

neuron

a nerve cell; the basic building block of the nervous system

pleurae

serous membranes that form an envelope between the lungs and the chest wall

Histology

study of tissues

simple epithelial tissue

single layer of cells

transitonal epithelium

function: to stretch without damage location: urinary tract, bladder

Merocrine

A strategy of secreting hormones via exocytosis

reticular fibers

Fibers made of collagen fibers that are very thin and branched. Forma tightly woven fabric that joins connective tissue to adjacent tissues.

WBC

white blood cell

areolar connective tissue

Function: wraps and cushions organs Location: widely distributed under epithelia of body

dense irregular connective

Function: able to withstand tension exerted in many directions; provides stuctural strength.

Location: Fibrous capsules of organs and of joints; dermis of the skin; submucosa of digestive tract.

bone connective tissue

-Support, protection

-Skeletal system

cardiac muscular tissue

Tissue in the heart (involuntary movement)

cutaneous membrane

The skin; composed of epidermal and dermal layers

Pericardium

Membrane surrounding the heart

epithelium

layer of skin cells forming the outer and inner surfaces of the body

stratified epithelium

several layers of cells

endothelium

lining of lymphatic vessels, blood vessels, and heart

Pseudostratified

This type of epithelial tissue appears to have multiple layers but all cells are in contact with the basement membrane

connective tissue

A body tissue that provides support for the body and connects all of its parts

Fibroblasts

In connective tissue, cells that secrete the proteins of the fibers.

hematopoietic

blood cell production

adipose connective tissue

acts as a storage depot for fat

dense elastic connective tissue

dense regular connective tissue containing a high proportion of elastic fibers

osteocyte

mature bone cell

smooth muscular tissue

Tissue in wall of internal organs (involuntary movement)

mucous membrane

specialized membranes that line the body cavities

peritoneum

membrane that lines the abdominal cavity

basal lamina

thin extracellular layer that lies underneath epithelial cells and separates them from other tissues

Squamous

flat cells

Mesothelium

the epithelium found in serous membranes lining the ventral body cavity and covering its organs

mucin

a complex glycoprotein that dissolves in water when secreted

ground substance

unstructured material that fills the space between the cells and contains the fibers

Chondroblasts

within the cartilage divide and secrete new matrix

Macrophages

Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.

reticular connective tissue

forms supporting tissue in walls of liver and spleen

hyaline cartilage

Most common type of cartilage; it is found on the ends of long bones, ribs, and nose

blood connective tissue

fluid extracellular matrix used to transport substances throughout the body.

intercalated discs

Attachment sites between the transverse lines between cardiac muscle cells

lamina propria

areolar connective tissue underlying a mucous membrane

goblet cells

a column-shaped cell found in the respiratory and intestinal tracts, which secretes the main component of mucus.

Avascular

without blood vessels

Cuboidal

cube shaped

gland

An organ that produces and releases chemicals either through ducts or into the bloodstream.

Holocrine

accumulate products within, then rupture (sebaceous oil glands)

Collagen

structural protein found in the skin and connective tissue

Osteoblasts

bone forming cells

Mesenchyme

embryonic connective tissue

dense connective tissue

tendons and ligaments

Elastic(cartilage)

outer ear

muscle tissue

A body tissue that contracts or shortens, making body parts move.

nervous tissue

A body tissue that carries electrical messages back and forth between the brain and every other part of the body.

serous membrane

Membrane that lines a cavity without an opening to the outside of the body
