Histology Lab: Microscopy of Dead Tissue


Down below are pictures that my group took of different kinds of tissues. Located under each picture is a description of the tissue above it. I hope you enjoy. 





Cardiac Muscle:
Description- branching, striated, generally uninucleate cells that interdigitate at specialized junctions 
Function- as it contracts, it propels blood into the circulation 
Location- the walls of the heart 



Skeletal Muscle:
Description- long, cylindrical, multinucleate cells
Function- voluntary movement; locomotion; manipulation of the environment; facial expression; voluntary control
Location- in skeletal muscles attached to bones and occasionally to skin







Puedo-stratified Columnar:
secretion and propulsion of mucus (makes mucus)





Stratified Squamous:
layers of thin epithelium cells, for protection to underlying layers and abration



Nervous Tissue:
Description- neurons are branching cells; cell processes that may be quite long extend from the nucleus-containing cell body; also contributing to nervous tissue are non irritable supporting cells
Function- transmit electrical signals from sensory receptors and the effectors which control their activity
Location- brain, spinal cord, and nerves





Transitional Epithelium:
stretches to permit the dissension of the urinary bladder
