What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
What is the term used to describe the crossing over of a tract to the side of the nervous system opposite to where the axons originated?
Decussation
Which nervous system division controls smooth muscle contraction and secretion in the digestive system?
Autonomous nervous system. Consisting of Parasympathetic nervous system and Sympathetic nervous system. Parasympathetic nervous system increases the secretions of digestive tract and Sympathetic system decreases the secretions. Parasympathetic system increases the contractions of smooth muscles and increases the rate and force of peristalsis and Sympathetic system does vise verse.

Which parts of the gastrointestinal tract are innervated by the somatic nervous system?
GI tract is innervated locally by the enteric nervous system and activity of the Cajal pacemaker cells and by the autonomic nervous system (sympathetic / parasympathetic). It is not innervated by the somatic nervous system. I'm a neurobiologist/physiologist.
A group of nerve fibers in the central nervous system?
A Tract
What part of the autonomic nervous system causes an increase in digestive tract mobility?
Stimulation of the Parasympathetic nervous system causes an increase in digestive tract mobility. When stimulated the parasympathetic post-ganglionic neurons release a hormone called Acetylcholine. This causes the Digestive tract to increase its contractions. Counteracting this increase in digestive tract mobility is the sympathetic nervous system, which releases a hormone called noradrenaline which slows down the digestive tracts contractions. This is how the Parasympathetic Nervous System gets the name "rest and digest"
What tract might be damaged if diminished sense of touch is observed?
Nervous system.
What is a bundle of nerve fibers within the central nervous system?
Called a tract.
What is descending tract and one ascending tract in upper motor neuron and lower motor neuron?
central nervous system (CNS) is the descending tract and one ascending tract in upper motor neuron and lower motor neuron.
What tissue helps with the movement of urine is it muscle or nervous through the urinary tract?
it is the muscle tissue
What parts of the nervous system controls digestion?
The parasympathetic nervous system is responsible for digestion. The GI tract is innervated by the Gastric nerve, otherwise known as the Vagus nerve.
Difference between optic tract and optic nerve?
Bundles of neuron processes are called tracts in the cns and nerves in the pns
How do rabits breathe?
Rabbits are mammals and breathe the same way that we do. They use their respiratory tract that is controlled by their nervous system.
What is the term used to describe the crossing over of a tract to the side of the nervous system opposite to where the axons originated?
Decussation
