The function of the GI tract is to process ingested food by mechanical and chemical means, extract nutrients and excrete waste products. The GI tract is composed of the alimentary canal, that runs from the mouth to the anus, as well as the associated glands, chemicals, hormones, and enzymes that assist in digestion.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The PNS includes motor neurons, mediating voluntary movement; the autonomic nervous system, comprising the sympathetic nervous system and the parasympathetic nervous system and regulating involuntary functions; and the enteric nervous system, a semi-independent part of the nervous system whose function is to control the gastrointestinal system.
The enteric nervous system functions to control the gastrointestinal system. Nerves that exit from the brain are called cranial nerves while those exiting from the spinal cord are called spinal nerves. The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the ...
The gut, sometimes referred to as the "second brain", may use the same type of neural network as the CNS, suggesting why it could have a role in brain function and mental health. [5] The bidirectional communication is done by immune, endocrine, humoral and neural connections between the gastrointestinal tract and the central nervous system. [4]
Olive oil provides essential nutrients and healthy fats that promote cardiovascular health, support brain function and enhance bone health. Its anti-inflammatory properties and antioxidants may ...
It is the most abundant neuropeptide in the central nervous system. [ 21 ] [ 22 ] CCK has been researched thoroughly for its role in digestion [ 23 ] In addition to its role in digestion, CCK is involved in regulating various behavioral phenomena, including satiety , appetite , anxiety , thermoregulation , sexual behavior, memory, and the ...
Through digestion, dietary carbohydrates are broken down and converted into glucose, which is the sole energy source for the brain. [5] [8] [11] Optimal brain function relies on adequate carbohydrate consumption, as carbohydrates provide the quickest source of glucose for the brain. [12]
