Question

Slightly movable joints have a cushion of _____ between them.
A. Matrix
B. Connective tissue
C. Plasma cells
D. Cartilage

Answer 1

Hint: These joints allow some flexibility but provide less stability than immovable joints.

Complete answer:
To solve this question, at first, we have to know the slightly movable joints. Slightly movable joints are known as amphiarthrosis. The singular form is amphiarthrosis. In this sort of joint, the bones are related through fibrocartilage. The ribs related to the sternum through costal cartilages are barely movable joints related through hyaline cartilage.
Now let us find the solution from the given options-

A) Matrix is the tissue in a eukaryotic organism's cells. The structure of connective tissues is an extracellular matrix. Fingernails and toenails develop from matrices. It is determined by many connective tissues.
B) Connective tissue separates and helps all different kinds of tissues present inside the body. Like all tissue kinds, it includes cells surrounded with the aid of using a compartment of fluid referred to as the extracellular matrix.
C) Plasma cells, additionally referred to as plasma B cells, are white blood cells that originate inside the bone marrow and secrete huge portions of proteins referred to as antibodies in response to antigens.
D) Slightly portable joints have only limited variety of movement and that is because of both fibrous tissue and cartilage. Some examples of this joint are: - Between the vertebrae of the spinal cord. Cartilaginous, or barely movable joints, have a cushion of cartilage in among the bones, with the bones resting on those beds of cartilage. This cushion of cartilage stops the bones from rubbing together.

Thus, the right answer is option D. i.e.Cartilage.

Note: These joints can be structurally divided as cartilaginous joints, as bones are related by cartilage at the joints. Cartilage helps to reduce friction between bones.
