Cells in the Nervous System
Tues Composer Nervous System
Nervous systems are composed of two types of cells:
- Neurons (nerve cells)
- Glia / neuroglia (supporting cells
Neurons
Role
Neurons are cells specialized to:
Neurons are cells specialized to:
- Reception (reception), conduction (delivery) and transmission (spread) the various signalsreceiving information and transmitting it to other cells
- Organize information from the body and the external environment, evaluating, sorting, selecting, integrating, coordinating, and deciding as needed
- The point is responsible for the human eye out everything you do: move, thoughts, memories, emotions
- Neurons in the adult brain of about 100 billion
Neuron classification - by form of branched
- Multipolar Neurons: neurons with dendrites that more than two out of its cell body
- Unipolar neurons: neurons with a branch coming out of the cell body, then the branch will be split in two
- Bipolar neurons: neurons with that branch out from the cell body on the side opposite
Neuron classification - by function
- sensory neurons: (input) carry messages from sensory organs to the brain and spinal cord
- the motor neurons: (output) sends the output from the brain and spinal cord to muscles and organs
- interneurons: (integration) input connector output
