The process in which movement of molecule from areas of high concentration to areas of low concentration is called diffusion . It is the passive movement of the atoms, molecule and particles. This movement remains continues until movement of ions, atoms and molecules are uniform throughout.
1 - The stimulus is received by sensory receptors.
2 - Sensory neurons carry stimulus information to the brain or spinal cord.
3 - The brain processes the information through interneurons.
4 - Interneurons transfer response information to motor neurons.
5 - Motor neurons cause muscles to contract so the body can react to the stimulus.
Explanation:
In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.
These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.
corticotropin releasing hormones (CRH) is another name for CRH factors. CRH is a 41 amino peptide which is derived from a 196-amino acid preprohormone which is it stimulate release of adrenocoticotropic hormone that is ACTH by the anterior pituitary which stimulate secretion of glucocorticoids from the adrenal cortex of the adrenal gland.
The answer to this item is letter "B. prostaglandin". Prostaglandins are hormones which are created during a chemical reaction at the site of the injury. Therefore, each cell has the ability to synthesize it. They also regulate several important processes in the body.
Neostigmine has a amine structure due to which it can cross the blood brain but once it gets absorbed it is secreted rapidly.
Disabled Urinary retention is a scenario in which the bladder never gets full. Neostigmine leads to accumulation of acetylcholine which triggers concentration based contractions in the urinary bladder. The muscarinic receptor on the urinary bladder contracts the bladder and the contraction gets stronger with passage of time
