Definition |
Where/More |
| Eptithelial tissue |
closely-joined cells classified by degree fo layering or shape |
on ALL free SURFACES |
| Simple |
Single layer |
|
| Stratified |
Multiple layers |
|
| Transitional |
Multiple layers of differnt types of epithelial tissues |
found in organs which EXPAND/CONTRACT often - URINARY BLADDER |
| Squamous |
flat, scaley |
|
| Cuboidal |
cubed |
|
| Columnar |
column shaped |
|
| Connective tissue |
ISOLATED groups of active cells, classified by physical properties of the matrix |
1. LOOSE connective tissue
2. DENSE connective tissue
3. VASCULAR connective tissue
4. CARTILAGES
5. BONE |
| Muscle Tissue |
elongated, densley-packed contractile cells (fibers) - classified by location and microanatomy |
1. Skeletal (striated)
2. Smooth (visceral)
3. Cardiac (heart) |
| Skeletal Muscle |
Striated, Multi-nucleated |
attached to bones - most in the body |
| Smooth Muscle |
Visceral, Non-striated, Tapered, Mono-nucleated |
surrounds hollows in organs |
| Cardiac |
Striated, Banded, Mono-nucleated, Branched |
Heart only |
| Nerve Tissue |
long, wirey cell processes, often with stellate bodies |
Brain and Spinal Column |
| Neurons |
Nerve Tissue |
impulse generation and conduction |
| Neuroglia |
Nerve Tissue |
supportive/insulative |
| Glands |
clusters (involutions/ducts) of epithelial cells |
usually cuboidal |
| Exocrine gland |
external secretion via a duct |
sebum, sweat |
| Endocrine |
internal secretion into the bloodstream |
|
| Body Membranes |
combinations of epithelia and connective tissue |
Mucous Membranes and Serous Membranes |
| Mucous Membranes |
different types of epithelium upon Loose connective tissue |
the lining of hollow organs (almost the entire GI Tract) - Functions: SECRETION and ABSORPTION |
| Serous Membranes |
Squamous epithelium over Loose connective tissue |
double lining of closed cavities: parietal layer = lines the cavity; visceral layer = covers the organ - Function: produces a watery secretion that REDUCES FRICTION |
| Areolar Tissue |
LOOSE Connective tissue - RANDOMLY placed cells (Fibroblasts and Macrophages)
Matrix: LONG, thread-like fibers made of COLLAGEN and ELASTIN protein. |
CONNECTS the SKIN to underlying TISSUE and fills spaces BETWEEN ORGANS.
-LARGE cells = MACROPHAGES
-SMALL cells = FIBROBLASTS
-THIN fibers = COLLAGEN
-THICK fibers = ELASTIN
|
| Adipose |
large FAT-filled cells, TIGHTLY packed in SPARSE, NON-fibrous matrix |
THROUGHOUT the body, especially UNDER the SKIN, amid SKELETAL muscle, and INSIDE long BONES |
| Hyaline Cartilage |
clumped cells (chondrocytes), invisible matrix |
forms CONNECTIONS between RIBS and STERNUM, at the ends of long bones, and surrounding the TRACHEA |
| Elastic Cartilage |
clustered chondrocytes scattered amid SHORT, WAVEY, ELASTIN fibers in a COLLAGEN matrix |
external EAR, EPIGLOTTIS, and EUSTACHIAN tubes |
| Fibrocartilage |
small cells, Matrix: PARALLEL bundles of COLLAGEN fibers |
ARTICULAR DISCS, in larger JOINTS, and PUBIC SYMPHYSIS |
| Compact Bone |
ISOLATED cells (osteocytes)in Matrix of inorganic SALTS and COLLAGEN; cells are arranged RADIALLY around HAVERSIAN CANALS |
ALL BONES of the skeleton |
| Blood |
RBC and WBC in liquid matrix (plasma) |
throughout the CIRCULATORY system |
| Haversian Canals |
house small BLOOD VESSELS and NERVE fibers |
in BONE |
BIOL3326 Forms
