The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
no, not all postganglionic sympathetic fibre neuron secrete NE
gray matter
the thalamic nuclei is made of unmyelinated axons which are gray matter
The cerebral cortex contains the bodies of neurons which appear grey (grey matter). The layer under the cortex contains myelinated axons (white matter).
parasynpathetic system
unmyelinated axons.
The connective tissue that covers unmyelinated and myelinated axons is called endoneurium.
no, not all postganglionic sympathetic fibre neuron secrete NE
Parasympathetic
could be preganglionic
Continuous conduction.
Adrenal Glands
Yes, myelinated axons are much more effective.
gray matter
Gray matter
Neuronal cell bodies, neuropil (dendrites and both unmyelinated axons and myelinated axons), glial cells (astroglia and oligodendrocytes) and capillaries.
