Nervous tissue is the body's communication network, specialized for receiving, processing, and transmitting information through electrical and chemical signals. Composed primarily of neurons and supporting glial cells, nervous tissue enables rapid responses to environmental changes and coordinates all body functions.
⥠Key Concepts
Neurons are specialized for communication
Electrical signals travel along cell membranes
Chemical signals cross synapses
Integration enables complex responses
Neural Speed
Nerve impulses can travel at speeds up to 120 meters per second - that's over 250 miles per hour, faster than most race cars!
đ¯ Learning Objectives
Understand neuron structure and function, learn how nerve impulses are generated and transmitted, and explore how nervous tissue integrates with other tissues.
