Chp 3.2 - Body Tissues and Membranes

Histology

Study of tissues

Epithelial Tissue

Cells that cover body surface or lines a body cavity

Simple Epithelia

Single cell layer of epithelial tissue

Stratified Epithelia

Two or more cell layers of epithelial tissue

Squamous Epithelia

Flattened and scale like epithelial tissue

Cuboidal Epithelia

Boxlike or cube shaped cells of epithelial tissue

Columnar Epithelia

Tall and column shaped cells of epithelial tissue

Goblet Cells

Secrete mucous in respiratory linings

Pseudostratified Columnar

Modified columnar cells that appear to be layered but are not

Transitional Cells

Special flat cells cememented together which can stretch

Gland

Cells that make and secrete a particular product

Secretion

Aqueous fluid that usually contain proteins

Endocrine

Internally secreting glands

Exocrine

Externally secreting glands

Ground Substance

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

Collagen Fibers

Strongest and most abundant connective tissue

Elastic Fibers

Connective tissue which allows for stretch and recoil

Reticular Fibers

Connective tissue which surrounds blood vessels and support organs

Fibroblast

Cells which make connective tissue

Chondroblast

Cells which make cartilage

Osteoblast

Cells which make bone

Hematopoietic Stem Cell

Cell which makes blood

Adipose Tissue

Fat

Axons

Long part of a nerve cell which transmits electrical impulses

Dendrites

Short part of a nerve cell which respond to stimuli

Vascularized

Contains blood vessels

Skeletal Muscle

Muscle which attaches to bone

Cardiac Muscle

Muscle which is located on the heart

Smooth Muscle

Non-striated muscle located in hollow organs
