Answer:
Repolarization
Explanation:
Complete repolarization is achieved by the sodium pump. This actively pumps all the Na+ ti the outside and all the K+ to the inside. The pump requires energy in the form of ATP and is inhibited by metabolic poisons. Entry of Na+ is immediately followed by an increase in the permeability of the membrane to K+. These diffuse rapidly to the outside due to the concentration gradient. Being positively charged, the K+ reverses the polarity of the membrane making the outside positive.
Answer:
Semicircular canals
Explanation:
Ear is one of the important sense organ responsible for hearing and equilibrium. Human ear is divided into three parts: outer ear, middle ear and inner ear.
Inner ear is mainly responsible for the equilibrium of the body. Vestibular apparatus together with semicircular canals is responsible for the dynamic equilibrium of the body. Dynamic equilibrium involves head rotation and vertical movements of the body.
Thus, the correct answer is option (a).
Answer:
Microglial cells
Explanation:
Microglial cells are one of the various types of neuroglial cells in the central nervous system. Microglial cells are the small cells and have thin slender processes. Many spine-shaped outgrowths come out of these processes. Microglial cells serve as phagocytes of the central nervous system. These cells clean the cellular debris that is generated during the normal development of the nervous system. Microglial cells also perform phagocytosis of microbes and damaged nervous tissue.
