Study Notes
Nervous Tissue
- Composed of two main cell types: neurons and neuroglia
Neurons
- Also known as nerve cells
- Develop from ectoderm
- Considered the functional unit of the nervous system
- Responsible for initiating, receiving, and transmitting information
- Are excitable cells
Neuroglia
- Glial cells
- Type of connective tissue
- Derived from mesoderm
- Do not transmit information
- Function to protect and support neurons
Functions of Neural Tissue
- Responsible for coordinating and controlling many body activities
- Stimulate and regulate processes in the body
- Facilitate integration and communication between various body parts
- Involved in higher-level functions such as intellectual processes, memory, and emotions
- Essential for sensation and response
