Question
Gray matter is composed of nerve cell bodies and dendrites. The cerebellum coordinates body movement, and plays a role in learning and in remembering motor responses. Sugar receptors in our tongue send higher voltage nerve impulses as the concentration of sugar increases. The Utricle, Saccule, Organ of Corti and Semicircular canals are all parts of the vestibular system of balance and perception of motion. Gradual inability of the eye to focus on nearby objects due to the lens losing its elasticity is known as nearsightedness Receptor cells that are found in taste buds and odor chemoreceptors found in our nasal cavities together produce the phenomenon known as flavor that we notice in different foods, etc. (so we can recognize what we are consuming). Photopsins are light absorbing visual pigments that are derived from vitamin A. There are normally seven cervical vertebrae in the human body. The type of bone where red marrow is found is called spongy bone. A muscle that works to perform the opposite movement of a particular muscles movement is said to be an antagonist muscle. Myofibrils are hundreds or more bundles of contractile proteins surrounded by Ca^++ ion-filled Endoplasmic Reticullum that are found in a single muscle fiber (skeletal muscle cell). Along with the presence of Actin (thin filament) and Myosin (thick filament), tropomyosin and troponin which make up the contractile apparatus of skeletal muscle, the two necessary chemical components needed to make contraction: actually occur are Ca^++ and ATP.Explanation / Answer
19.The central nervous system is made up of two types of tissue known as grey matter and white matter. The grey matter is mainly composed of nerve cell bodies as well as non-myelinated axons (cell bodies) and is involved in the information processing system of the brain.
So, the correct option is "TRUE"
