延髓 (Medulla)
What role do spinal tracts play in the peripheral nervous system?
Spinal tracts are communication pathways. There are numerous tracts and they carry messages from the body to the brain and from the brain to the body.
Descending tracts within the spinal cord carry what kind of impulses to the muscles?
To make it simple, they are 3 types of descending (efferent) tracts of spinal cord:Pyramidal tracts = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal tracts= Vestibulospinal + Reticulospinal (Lateral and medial) + Olivospinal + Rubrospinal + Tectospinal tractsDescending autonomic
Why do messages not get mixed up passing through the spinal cord?
There are ascending and descending tracts in the spinal cord. These tracts are nerve fibers bundled together. Messages going to the brain pass through the ascending tracts while messages coming from the brain pass through the descending tracts. These separate paths prevent messages from getting mixed up.
What is the function of the Nucleus and location?
It is like the brain of the cell, so it orders everything around.
What is a brain lesion?
A brain lesion is damage caused on purpose to a very specific location in an animal's brain. This method is used in lab experiments, since it allows us to research a specific location's function in the brain by observing the effects of its lesion.
What tracts of the spinal cord carry impulses away from the brain?
synape
What tracts of the spinal cord carry sensory information to the brain?
spinothalamic
What tracts the spinal cord carry sensory information to the brain?
spinothalamic
Messages are carried from the eyes to the brain by?
The optic nerve and optic tracts.
What are the names of the cells in your brain?
Brain cells are called neurons. There are many different classifications of neurons - by size, shape, location, function, and so forth.
What impulses do ascending tracts within the spinal cord carry to the brain?
reflex
