Document Summary
Dendrite recieves information from other neurons and relays it to cell body. Cell body coordinates information processing tasks and keeps cell alive. Axon transmits information to other neurons, muscles or glands. Myelin sheath insulating layer of material made up of glial cells (some digest dead neurons, others provide physical and nutritional support, others form myelin) Synapse area between axon terminal and dendrite. Types of neurons: sensory neuron, receive information from the external world and convey information to brain via spinal cord, motor neuron, neurons that carry signals from spinal cord to the muscles. Interneuron: most neurons are these neurons which connect motor and sensory neurons and performs a variety of information-processing functions. Purkinje cells: neuron that carries information from cerebellum to the rest of brain and spinal cord. Hippocampal pyramidal cell: found in cerebral cortex, they have a triangular cell body and one long dendrite along with other small ones.
