1 Tissue ID-ing Practice
Practice for the histology test


3 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

4 2. ?

5 Simple Cuboidal Description: Single layered cubelike cells Function: to absorb and secrete Location: Kidney, ovary surface


7 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


9 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


11 Stratified Squamous Description: Multi-layered with a squamous apical surface Function: To protect underlying tissues from abrasion Location: Mouth, linings of the esophagus


13 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


15 Hyaline Description: Smooth firm matrix Function: support and reinforce Location: trachea, larynx


17 Elastic Description: Similar to hyaline, but more elastic fibers in matrix Function: Maintains shape of structure and allow flexibility Location: external ears (pinna)


19 Fibrocartilage Description: Matrix is similar but less firm than hyaline Function: ability to absorb compressive shock. Location: intervertebral discs, discs of knee joint


21 Osseous (Bone) Tissue Description: hard, calcified matrix containing collagen fibers Function: Bone supports and protects: lever for muscles to act on Location: Bones


23 Blood Description: Red and white blood cells in a fluid matrix Function: transport respiratory gasses and nutrients Location: within blood vessels


25 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


27 Skeletal Muscle Tissue Description: Striated, long, cylindrical Function: Voluntary movement, facial expression, control Location: attached to bones


29 Cardiac Muscle Tissue Description: Striated, branching, has intercalated discs Function: Involuntary control; propels blood into circulation. Location: Walls of heart


31 Smooth Muscle Tissue Description: central nuclei, no striations, sheet-like Fuction: Propels substances along internal passageways; involuntary control Location: Walls of hollow organs


33 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


35 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
