Nervous system -JM Flashcards
What are multipolar neurones?
The CNS and motor neurones
There have lots of dendrites
What are bi-polar neurones?
Relay neurones
They have an axon and a dendritic process
What are pseudo-unipolar neurones?
Sensory neurones
From CNS to periphery
Cell body out the side
What are neuroglia?
Cells that support the neurones
What is a ganglion?
A bundle of nerve cell bodies outside the CNS
What are plexi?
A big network of peripheral nerves
What are axons wrapped in?
Endoneurium
What is a bundle of axons called?
A fascicle
same as a bundle of muscle fibres
What is a fascicle wrapped in?
Perineurium
What are multiple fascicles wrapped in?
Epineurium
What are intumescences?
Enlargements of the spinal cord due to lots of cell bodies/plexi going to the limbs
What is the corda equina?
Tasselled end of the spinal cord where there is disproportionate growth
What is found at the dorsal horn of the grey matter in the spinal cord?
Sensory neurones
What is found in the ventral horn of the grey matter in the spinal cord?
Somatic motor neurones and their cell bodies
Where do somatic motor neurones go?
Skin and skeletal muscle
