from the brain that carries nerve impulses to and from the body along with blood vessels. All vertebrates have spinal and cranial nerves associated with the brain and spinal cord. Also many systems are needed to maintain and control features of the body. For example the endocrine‚ autonomic‚ and peripheral systems are needed for full normal function of the animal. The ability to process information is very important. This involves the brain stem‚ many motor nerve cells‚ basal ganglia‚ and other

microvilli that project through pores and chemically sense food. Gustatory receptor cells communicate with cranial nerve axon endings to transmit sensation to the brain. There are five taste sensations located on the tongue. They are sweet located front middle‚ sour located middle sides‚ salty located front side/tip‚ bitter located back‚ and umami located posterior pharynx. The cranial nerves that are associated with our taste sense are VII Facial located within the tongue‚ IX Glossopharyngeal located

What part of the brain transmits motor impulses from Annette’s basal nuclei to her primary motor area? The thalamus transmits motor impulses from Annette’s basal nuclei to her primary motor area. F. Motor signals from Annette’s primary motor area in her cerebral cortex must travel to the cerebellum so that she can pick up her fork. What

1) What is the role of calcium ions during contraction of a skeletal muscle? Calcium is an important element for live. Calcium is found in the bones of animals and humans. In muscle contraction is produce as a result of Calcium ions ‚ Ca2+‚ It comes from rapid release from the cisternae of the sarcoplasmic reticulum which cause a chemical reaction between ATP and the myofilaments. Another important function of Calcium ions occurs during the state of resting muscle. During the state of resting

Some cells are activated only by lines of particular width‚ shape‚ or orientation; while other cells are activated only by moving. Different parts of the brain process nerve impulses in several individual systems at the same time. Color vision is based on two processes or theories; trichromatic theory and the opponent-process theory. The trichromatic theory states there are 3 kinds of cones in the retina‚ to which each is
