what is the function of nerve tissue?
processes sensory information from sensory organs and responds with motor instruction to the body muscles and glands
what are neurons ?
cells responsible for retrieving, interpreting, and sending the electrical signals of the nervous system
what are neuroglia/glial cells
support cells that surround and wrap neurons
what is the order of the structure of neurons
dendrite, soma cell , axon fibers, schwann cell, axon terminals
what do dendrites do ?
collects sensory messages to send to
what does the axon do?
transmits messages down neuron towards a muscle or gland
what does the schwann cells do?
glial cell that increases the speed of message transmission
what do axon terminals do?
communicates with adjacent cells via neurotransmitters
how are messages sent through the neurons ?
nerves respond to environmental change by processing stimuli into electrical impulses or action potentials
list the steps of neuron communicate(send messages from one neuron to the next)
1. Dendrites receive sensory input
2. the signal is conducted down the axon
3. the axon terminals release neurotransmitters (chemical messages) into the synapse
4. the neurotransmitters excite or inhibit other cells
