it allows humoral factors in hypophyseal portal circulation or systemic circulation to access hypothalamic nuclei via retrograde axonal transport (i.e. feedback regulation of pituitary hormones)
The function of this tract is to detect pain.
Cllulose has important function on movement of material in digestive tract
Below is a greatly simplified sketch of the vocal tract. In the sketch, "supra-laryngeal" means "above the larynx"; "subglottal" means "below the vocal cords." Although the diaphragm is usually included in the parts of the vocal tract, its only function in speech is to help draw air into the lungs; it has only a passive function in the outgoing flow of air that is used for both speech and breathing. If you think of those structures from the viewpoint of a "vocal tract," then their primary function is for speech. But from knowledge of the parts of the vocal tract, you can see that the structures have other functions, particularly those that serve respiration and ingestion. The vocal tract serves too many functions to list on a message board, but among those functions are breathing for life; protecting the airway from particles that might either block it or injure it; taking in food and beginning the digestive process in the mouth; preventing solid food and liquids from entering the nasal cavity or the lungs.
tract
This fiber tract is called the projection tract.
The function of this tract is to detect pain.
The function of the projections of the mucosa of the GI tract is secretions and absorption. Digestion is also aided by these projections.
Several systems do this function, the kidneys, the respiratory tract, the lower digestive tract and the skin.
the oesophegus
transferring and extracting nutrients
To support the mucosal lining of the gastrointestinal tract.
The beginning of the opening of the second part of the digestive tract
The olfactory tract is a bundle of axons connecting the mitral and tufted cells of the olfactory bulb to several target regions in the brain.
Cllulose has important function on movement of material in digestive tract
Probably it is an intermediate pathway in the strio-olivo-spinal connections
break down food into nutrients the body can use
The digestive tract basically breaks down the macromolecules into monomers to be absorbed into the body. Various enzymes are involved in the process of digestion. Digestive tract in humans starts from the mouth and ends at anus.
