TISSUES
Epithelial Tissue
a sheet of cells that covers a body surface or lines a body cavity
Simple Squamus Epithelium
- allows passage of materials by diffusion and filtration
Simple Cuboidal Epithelium
- secretion & absorption
Simple Columnar Epithelium
- absorption & secretion of mucus, enzymes, and other substances
Stratified Squamus Epithelium
- protects underlying tissue
Stratified Cuboidal Epithelium
- protection
Stratified Columnar Epitheliium
- protection & secretion
Transitional Epithelium
- stretches readily
4 Major Functions:
It protects underlying tissues
It absorbs
It secretes
Epithelial tissue excretes
Epithelium tissue is given 2 names:
Number of cell layers
Simple
- one layer
Stratified
- more than one layer
Shape of its cells
Squamus
- flat
Cuboidal
- cube
Columnar
- rectangular
Connective Tissue
tissue that connects other tissues in the body
3 Types of Fibers:
Collagen Fibers
- most abundant
Elastic Fibers
- contains elastin
Reticular Fibers
- found in liver & bone marrow
General Functions:
enclose & separate organs
connect tissues
support & movements
storage
cushion & insulation
transport
Loose Connective Tissue
Areolar Connective Tissue
Reticular Connective Tissue
Adipose Connective Tissue
Dense Connective Tissue
Dense Irregular Connective Tissue
Dense Regular Connective Tissue
Elastic Connective Tissue
Specialized Connective Tissue
Bone Connective Tissue
Cartilage
hyaline cartilage
elastic cartilage
fibrocartilage
Muscle Tissue
contractile animal tissues that produce power and locomotion
3 Types of Muscle Tissue:
Skeletal
- can be attached to bone
Cardiac
- located in the walls of the heart
Smooth
- controls the size of the pupil of the eye
5 Major Functions:
Movement
Support
Protection
Heat Generation
Blood Circulation
Nervous Tissue
consist of neurons or nerve cells & supporting cells or neuroglia or glial cells
Neurons
cells with the nervous system that transmit information
3 General Structures:
Dendrites
Cell Body
Axon
Neurotransmitter
Synapse
Neuroglia or Glial Cells
Major Functions:
Cell Body
- regulates the functioning of the neurons
Axon
- carries impulses away from the cell body
Neurotransmitter
- transmit impulses across synapses
Dendrites
- carries impulses toward the cell body
Synapse
- transmits impulses from one neuron to other
Neuroglia
- from myelin sheaths and other functions
Schwann Cells
- from the myelin sheaths around neurons
