endoneurium
P

fibrous perineurium
PE

What would all of these be called?

myelinated nerve fibers
asterik

myelnated axon
arrow

lemmocyte
arrow

lemmocyte cytoplasm
arrow

myelin sheath (myelin neurokeratin)
arrow

myelin node (node of Ranvier)
What are these?

non-myelinated nerve fibers

central canal (of spinal cord)
arrows

epedymal cells (lining central canal)
red box

white matter
DF, LF, VF

funiculi (dorsal, lateral, & ventral)
blue box

grey matter
arrows

dorsal grey horns
black arrows

ventral grey horns
What type of cell are these? Where are they found?

Purkinje cells (cerebellar cortex)
thick arrow

dendrites
What type of neurons are these? Where are they found?

- bipolar neuron
- retina
1?2?3?

1 - bipolar
2 - unipolar
3 - multipolar
red box

nissl bodies (substance) (cytoplasmic RER)

nucleus

nucleolus
What is the perikaryon?
the cell body
red box

axon
What are these?

astrocytes
Green box (where found)? Red Box (whre found)

- fibrous astrocyte (in white matter)
- protoplasmic astrocyte (in grey matter)
WHAT ARE THESE? how are they DifERENT from astrocytes?

- oligodendrocytes
- smaller, fewer processes
What are these? What kind of neurons are these? What are the cells surrounding each perikarya?

- spinal ganglia
- unipolar neurons
- satellite lemmocytes
What is this thing? What type of thing is it?

- Pacinian corpuscle
- receptors
What is this? How are they different from Spinal ganglion?

- Autonomic Ganglion
- Autonomic are multipolar neurons, fewer lemmocytes, smaller cell bodies
1D 2A 3* 4P 5W

- Dura Mater
- Arachnoid (Arachnoid membrane)
- Subarachnoid space
- Pia Mater
- White matter of the spinal cord
What is this thing? What type of neuron is it?

- Motor Neurons in ventral horn
- somatic efferent neuron
