neurons and neuroglia

soma (cell body)

The central part of a neuron that contains the nucleus and is responsible for maintaining the cell's health and functioning.

dendrites

recieves signals

axon

transmits signals away from the cell body

axon terminal

The ending part of an axon that releases neurotransmitters to communicate with other neurons or target cells.

nucleus

The membrane-bound organelle in a cell that contains genetic material and controls cellular activities.

nodes

allow nerve impulses jump from gap to gap

myelin sheath

speeds up transmission of electrical signals

astrocytes

star-shaped cells, provides support to neurons, helps form blood barrier and help move nutrients and control ion balance

olidendrocytes

wrap around the neurons in CNS and help create myelin sheath

microglia

brains clean up crew, scans for damaged cells/ clean up debris in brain

ependymal cells

line the brain’s ventricles and help produce and circulate cerebrospinal fluid which cushions brain and spinal cord

satellite cells

surround and support the neuron cell bodies in the PNS helping them get nutrients and maintain a healthy environment.

schwann cells

wraps around neurons in the PNS to create myelin sheath
