Answer:
The correct answer is OPTION C (Circumduction)
Explanation:
Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
The cells directly responsible for cellular immunity are the cytotoxic T cells (lymphocytes).
Cellular immunity is an immune response against infectious diseases caused by viruses and some bacteria. This mechanism does not involve antibodies, but rather cytotoxic T-lymphocytes, phagocytes and the release of cytokines in response to an antigen. <span>Cytotoxic T cells, perform their function by killing infected cells via apoptosis.</span>
