1. Histology The microscopic study of tissue.
It is important to know the structure and function of tissues
In order to understand how individual cells are organized
And how tissues work to form organs and organ systems.

2. Learner Objectives
To analyze the relationships between the structures and functions of tissues.
To evaluate the cause and effect of disease and trauma on the structure and function of tissues.

3. 3 types are classified by structure and function:
Muscle Tissue
Muscle tissue is contractile, and through contractions is designed to move the body, pump blood, and decrease the size of hollow organs.
3 types are classified by structure and function:
Skeletal
Cardiac
Smooth

Nervous Tissue
Conducts electrical signals called “action potentials”
Neurons – nerve cells – composed of 3 parts: cell body, dendrites, and axons.
Types of neurons:
Multipolar
Bipolar
Unipolar
Support cells – support cells of the brain, spinal cord, and peripheral nerves. Also form myelin sheaths around axons and produce cerebrospinal fluid.
Schwann cells
neuroglia
