Exocrine

       
Endocrine

       
Unicellular

2. Which of the following is responsible for the synthesis of cerebrospinal fluid (CSF)?

      
Microglial

       
Ependymal cells

       
Osteoblast

       
Medulla Oblongata

       
Insula

3.

What condition is result from the failure of the papillary muscles?

      
The coronary arteries collapes

       
The semilunar valves prolapse

       
Blood to leak through the semilunar valves

       
Left ventricular failure

       
The AV valves to prolapse

Answer 1

Ans.1. Option A is the correct answer.

EXPLANATIONS:- The sweat glands are the modified exocrine glands. The exocrine gland have the ducts. So they are also called as the duct bearing glands. These glands secrete their secretion on surface. So due to the improper development of the exocrine gland, their legs do not sweat.

Ans.2. Option B is the correct answer.

EXPLANATIONS:- The ependymal cells are responsible for the secretion of the CSF. The CSF stand for the cerebrospinal fluids. The CSF protects the brain.

Ans.3. Option C is the correct answer.

EXPLANATIONS:- Due to the failure of the papillary muscles blood will leak through the semilunar valve. The semilunar valve are also called as the tricuspid valve. They have the three cusps that's why they are called as the tricuspid valve. They prevents the back follow of blood. But due to failure of the papillary muscle they will not work. The are present on the right chamber of heart.
