Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
Answer:
The correct answer is C.
Explanation:
The respiratory center is divided into 3 main groups, the dorsal respiratory group and the ventral respiratory group, both located in the <u>medulla</u>, and the pontine respiratory group, located in the <u>pons</u>. This last one also divides into two areas: <em>the pneumotaxic and the apneustic center.</em>
During quiet, restful breathing, the dorsal group stimulates the diaphragm and the intercostal muscles for inspiration. Expiration then occurs depending on the elastic recoil of the lungs. When forced expiration is required, the ventral group activates.
Answer:
Standard <u>anatomical
</u> position is the agreed-upon reference for body position when studying anatomy (option 2).
Explanation:
Anatomical position consists of the placement of the human body for its anatomical study, following certain norms established and accepted by convention.
- <em>The body is observed from its front face.
</em>
- <em>The members must be extended, showing their ventral surface and with a slight separation from the rest of the body.
</em>
- <em>The hands show the palms, while the feet are hyperextended showing their backs.
</em>
This position is useful to provide the description of any area of the body in a specific posture, and that can be understood even by those who do not observe.
The other options are not correct because:
<em> 1) </em><u><em>Histological</em></u><em>, refers to the study of cells and tissues.
</em>
<em> 3) </em><u><em>Superior</em></u><em>, is a directional term, indicating something located at the top of the body or closer to the head.
</em>
<em> 4) </em><u><em>Mnemonic</em></u><em> refers to the association of words used to remember names or lists of names.</em>
