Tissue ID-ing PracticePractice for the histology test

Simple squamous

Description: Single layered flattened cell, nuclei is centered

Function: to allow passage for materials where security is not important; secretes lubricating substances

Location: Kidney, air sacs of the lungs

2.?

Simple Cuboidal

Description: Single layered cubelike cells

Function: to absorb and secrete

Location: Kidney, ovary surface

Simple Columnar

Description: single layer tall cells with round to oval nuclei..a little bit of cilia

Function: To secrete and absorb mucus

Location: stomach, anal canal

Pseudostratified epithelium

Description: Looks like simple columnar but with more cillia and contains goblet cells..differing heights

Function: To secrete mucus through ciliary function

Location: linings of the trachea, male sperm carrying duct

Stratified Squamous

Description: Multi-layered with a squamous apical surface

Function: To protect underlying tissues from abrasion

Location: Mouth, linings of the esophagus

Transitional Epithelial

Description: resembles both stratified squamous and cuboidal; basal cells are cuboidal and columnar

Function: to allow organs to expand when contained with urine

Location: bladder

Hyaline

Description: Smooth firm matrix

Function: support and reinforce

Location: trachea, larynx

Elastic

Description: Similar to hyaline, but more elastic fibers in matrix

Function: Maintains shape of structure and allow flexibility

Location: external ears (pinna)

Fibrocartilage

Description: Matrix is similar but less firm than hyaline

Function: ability to absorb compressive shock.

Location: intervertebral discs, discs of knee joint

Osseous (Bone) Tissue

Description: hard, calcified matrix containing collagen fibers

Function: Bone supports and protects: lever for muscles to act on

Location: Bones

Blood

Description: Red and white blood cells in a fluid matrix

Function: transport respiratory gasses and nutrients

Location: within blood vessels

Nervous Tissue

Description: branching cells surrounded by supporting cells (neuroglia)

Function: Transmit electrical signals from sensory receptors to effectors; control activity

Location: brain, spinal cord, nerves

Skeletal Muscle Tissue

Description: Striated, long, cylindrical

Function: Voluntary movement, facial expression, control

Location: attached to bones

Cardiac Muscle Tissue

Description: Striated, branching, has intercalated discs

Function: Involuntary control; propels blood into circulation.

Location: Walls of heart

Smooth Muscle Tissue

Description: central nuclei, no striations, sheet-like

Fuction: Propels substances along internal passageways; involuntary control

Location: Walls of hollow organs

Areolar Tissue

Description: Gel-like matrix with all three fibers: Elastic, Collagen and fibroblast fibers

Function: wrap and cushion organs; provide protection and holds tissue fluid

Location: under epithelia

Adipose Tissue

Description: Made up of close packed adipocytes which are fat cells. Nuclei pushed to the side

Function: Provides reserve fuel and organ protection

Location: Breast, within the abdomen
