What is structure 2?
Axon Hillock
What is structure 1?
Dendrite
What is structure 3?
Axon
What is structure 4?
Nissel Bodies
The space between myelin sheath and the site where Na+ and K+ exchange occurs, as down in struture 1, is called what?
Nodes of Ranvier
What is the outer covering of the nerve as shown in structure 1?
The epineurium.
A bundle of neurons is grouped into a unit, shown in struture 2, called…
fasicles.
The lining that covers fasicles, as shown in structure 3, is called…
perinurium.
Individual neurons, are covered by this structure (structure 4, in the composition of a nerve drawing)..
endonurium.
In the composition of a nerve drawing, what is structure 4?
Individual neurons.
In the spinal nerves drawing, what is structure 1?
White matter
In the spinal nerves drawing, what is structure 2?
the central canal
In the spinal nerves drawing, what is structure 3?
dorsal root ganglion
Neurons entering through the dorsal/posterior rami are afferent or efferent neurons?
Afferent or nerves carring informtion into the spinal cord.
Neurons exiting through the anterion rami of the spinal cord are afferent or efferent?
efferent, these nerves carry outgoing messages.
In the spinal nerves drawing, what is structure 4?
axons of afferent neurons.
In the spinal nerves drawing, what is structure 5?
dendrites of afferent neurons
In the spinal nerves drawing, what is structure 6?
mixed nerve containing both efferent anf afferent neurons.
In the spinal nerves drawing, what is structure 7?
axon of efferent neuron
In the spinal nerves drawing, what is structure 8?
Grey matter
In the spinal meninges diagram, what is structure 1?
Dura mater
In the spinal meninges diagram, what is structure 2?
arachnoid mater
In the spinal meninges diagram, what is structure 3?
pia mater
In the spinal meninges diagram, what is structure 4?
subarachnoid space
