Answer:
Sternocleidomastoid is the muscle which when when contracted unilaterally, will produce lateral bend of the spine
Explanation:
Sternocleidomastoid muscle is responsible for the turning of neck and its nodding. It consists of long muscles that are able to connect the three process of temporal bones i.e sternum, clavicle, and mastoid. Thus, this muscle can bend the spine laterally.
I think this picture is very helpful
Option B
Middle colic arteries is the most likely additional source of blood to the descending colon
<h3><u>
Explanation:</u></h3>
The middle colic artery is a section of the superior mesenteric artery. Middle Colic provides the transverse colon, has a branch that runs to the right colon and branch that persists to the left colon that catches up with the left colic artery and proceeds as the marginal artery to provide the descending colon.
The left gastroepiploic artery is one of the sections of the splenic artery. Sigmoid- branch off IMA so barred in this case Splenic- proceeds of the celiac trunk, branches accumulation spleen & pancreas Superior Rectal- a sequence of IMA not possible to participate in this case
Answer:
D. Tricuspid → right ventricle → pulmonary valve → pulmonary circulation
Explanation:
The circulatory system is the system of organs and blood vessels which is associated with the circulation of the blood in the body.
The circulatory system is divided into two portions: the systemic circulatory system (body) and the pulmonary circulatory system (lungs).
The vena cava brings the oxygen-poor blood from the body to the right atrium from where the blood is transferred to the same side of the ventricle controlled by the tricuspid valve (atrioventricular valve).
From the right ventricle, the blood is pumped to the pulmonary artery which transports the blood to the lungs where the oxygen will be exchanged.
Thus, Option-D is correct.
