A sensory map is an area of the brain which responds to sensory stimulation, and are spatially organized according to some feature of the sensory stimulation.In some cases the sensory map is simply a topographic representation of a sensory surface such as the skin, cochlea, or retina.
The cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker via two sets of nerves: sympathetic fibres, part of the autonomic nervous system, to make heart rate faster. the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Fourth ventricle location shown in red (E), pons (B); the floor of the ventricle is to the right, the roof to the left. The fourth ventricle has a roof at its upper (posterior) surface and a floor at its lower (anterior) surface, and side walls formed by the cerebellar peduncles (nerve bundles joining the structure on the posterior side of the ventricle to the structures on the anterior side).
The vasomotor center is a collection of integrating neurons in the medulla oblongata of the middle brain stem.The term "vasomotor center" is not truly accurate, since this function relies not on a single brain structure ("center") but rather represents a network of interacting neurons.
The picture displays the mediastinum on sagittal plane, thoracic diaphragm at the bottom, the heart (cor), behind sternum and ribs (to the left on the picture (this is the anterior/front) and to the right (posterior/back)), you have the thoracic vertebrae.
Since the area postrema acts as an entry point to the brain for information from the sensory neurons of the stomach, intestines, liver, kidneys, heart, and other internal organs, a variety of physiological reflexes rely on the area postrema to transfer information. The area postrema acts to directly monitor the chemical status of the organism.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
