Alexis is out mowing the lawn and starts to feel dehydrated. Her ______ will secrete vasopressin. A patient suffering from sever
adoni [48]

1. The right answer is - Hypothalamus (manufactured by the hypothalamus, stored in the pituitary gland).

Vasopressin, or antidiuretic hormone, is a peptide hormone synthesized by the supraoptic and paraventricular nuclei of the hypothalamus, and released by the posterior pituitary gland (neurohypophysis).

It mainly has an anti-diuretic role in the kidney, where it causes a reabsorption of water via an action on the distal segment of the nephron during a dehydration body. Its gene is AVP located on human chromosome 20.


2. The right answer is - Increased Secretion of Vasopressin To Maintain Less Loss Of Water.

Vasopressin has an antidiuretic action: it decreases the volume of urine by increasing the water permeability of the collecting tube. It binds to the V2 receptor, which is coupled to a Gα protein, which activates a signaling cascade through the PKA. This causes the synthesis of aquaporin 2 (transmembrane pore) as well as its translocation to the apical / urinary membrane.

Recall what you know about nervous tissue to answer the following questions. Nervous tissue can generate and conduct ____ signal
Dimas [21]

Answer:

Nervous tissue can generate and conduct <u>electrical</u> signals that control the body.

Explanation:

The neuron is the specialized cell that provides function to nerve tissue. Given the structure of the neuron, this cell is capable of creating and conducting information in the form of electrical impulses or signals, by depolarizing its cell membrane and generating action potentials.

The information generated and transmitted by the neurons allows the nervous system to obtain internal and external information of the organism, as well as to control all the body functions.

<em>     The other options are not true because nerve tissue does not generate or conduct </em><em>thermal </em><em>or</em><em> chemical </em><em>signals to perform its function.</em>
