Biol 65 SJSU Final questions and
answers
What is all included in a nerve cell?✔✔- Nucleus
- Dendrites ( tree-like branches )
- Myelinated Axons ( helps move faster )
- Nissil Substance ( aka rough er)
- Axon hillock
- Myelin sheath ( protection later )
- Schwann cells ( help with nerve regeneration)
- Nodes of Ranvier ( gaps )
- Telodendria ( branches @ end )
- Neuromuscular junctions (helps convert action potential)
- Skeletal muscle fiber
- endoneurium ( fiber that helps w/ protection n nutrients)
What is the point of the neuron?✔✔This helps communicate to and control the body
What are the 3 functions of the nervous system?✔✔- sensory: pns to cns afferent
- integration: sensory
- motor: cns to pns efferent
What are the two systems that help with the basic of the nervous system?✔✔The
central nervous system which is the brain and spinal cord
and
The Peripheral nervous system which is everything else
What is glial cells and what is their purpose to the nervous system?✔✔essential
provide the framework to help support neurons and their activities
What is the purpose of neurons to the nervous system?✔✔The main importance is
to communicate with the nervous system
What are the two different types of matter in the brain?✔✔there is white matter and
grey matter. White matter contains the myelinated axons and grey matter contains
cell bodies and dendrites
What is a ganglion and where is it found?✔✔This is a cluster of neurons and it is
found in the peripheral nervous system
What are the different systems involving the nervous system✔✔- the CNS
- The PNS
- The ANS
How many types of neuron classifications are there?✔✔- multipolar containing 3
more
- bipolar 2 or more processes
