Primary sensory areas 1 Olfaction is the only sensory system that is not routed through the thalamus.  Vision: The visual area known as V1, striate cortex, or (primary visual cortex, Brodmann area 17) is located on the calcarine sulcus deep within the inside folds of the occipital lobe.

Regulation of Blood Pressure: Short Term Regulation & Baroreceptors Blood pressure is constantly monitored by your body and adjusted constantly to meet the needs of your body. This monitoring is performed by baroreceptors. Baroreceptors are special receptors that detect changes in your blood pressure.

- Several important nuclei are located in the midbrain, including the red nuclei, the substantia nigra, and the nuclei of cranial nerves III and IV. The red nuclei connect the midbrain to the cerebellum and to the inner ear.

Background Changes in stretch and transmural pressure are detected by baroreceptors in the heart, carotid sinus, aortic arch, and other large vessels. Afferent impulses are transmitted by the carotid sinus, glossopharyngeal, and vagus nerves to the nuclei tractus solitarius and the para median nucleus in the brain stem.

What are Baroreceptors? Arterial baroreceptors respond very quickly to changes in blood pressure, firing more rapidly as blood pressure increases, resulting in a lowered heart rate and lowered blood vessel resistance. When they stop firing, the central nervous system responds by increasing heart rate and blood vessel resistance.

- The baroreceptor reflex or baroreflex is the body's way of responding to a change in blood pressure. Baroreceptors in the arteries notice that something has changed. When they sense a change in pressure, they send out signals through nerves to a part of the brain called the brainstem. The increase in pressure causes more signals to be sent to the brainstem.

- In vertebrates, the olfactory receptors are located in both the cilia and synapses of the olfactory sensory neurons and in the epithelium of the human airway. In insects, olfactory receptors are located on the antennae and other chemosensory organs.he primary sequences of thousands of olfactory receptors (ORs) are known from the genomes of more than a dozen organisms: they are seven-helix transmembrane proteins, but there are (as of July 2011) no known structures of any OR.

- The sensory impulse that is generated here travels along afferent fibers to cell bodies located in a dorsal root ganglion and from there to the spinal cord. Within the spinal cord, the afferent fibers synapse on the cell bodies of efferent neurons, whose long axons extend to innervate muscles in the leg.

Olfaction Olfactory sensory neurons project axons to the brain within the olfactory nerve, (cranial nerve I). These nerve fibers, lacking myelin sheaths, pass to the olfactory bulb of the brain through perforations in the cribriform plate, which in turn projects olfactory information to the olfactory cortex and other areas.he sensory receptors of the accessory olfactory system are located in the vomeronasal organ. As in the main olfactory system, the axons of these sensory neurons project from the vomeronasal organ to the accessory olfactory bulb, which in the mouse is located on the dorsal-posterior portion of the main olfactory bulb.

Regulation of Blood Pressure: Short Term Regulation & Baroreceptors Second, if the baroreceptors are detecting that blood pressure is too high, the cardio regulatory center of the medulla will also decrease sympathetic input to the blood vessels. This causes vasodilation, which decreases total peripheral resistance and decreases blood pressure.

- Important baroreceptors are found in the aorta and the carotid sinus. If the blood pressure within the aorta or carotid sinus increases, the walls of the arteries stretch and stimulate increased activity within the baroreceptors.he opposite happens when the baroreceptors of the aorta and the carotid sinus detect a drop in blood pressure. In this case, the cardio regulatory center responds to the low blood pressure by causing an increased heart rate and causing vasoconstriction.

Sense of Touch Thermoreceptors are found all over the body, but cold receptors are found in greater density than heat receptors. The highest concentration of thermoreceptors can be found in the face and ears (hence why your nose and ears always get colder faster than the rest of your body on a chilly winter day). Pain receptors: The scientific term is nocireceptor.

Mechanoreceptors Cutaneous mechanoreceptors are located in the skin, like other cutaneous receptors. They are all innervated by Aβ fibers, except the mechanorecepting free nerve endings, which are innervated by Aδ fibers. They can be categorized by morphology, by what kind of sensation they perceive and by the rate of adaptation.

Baroreceptor Arterial baroreceptors are stretch receptors that are stimulated by distortion of the arterial wall when pressure changes. The baroreceptors can identify the changes in both the average blood pressure or the rate of change in pressure with each arterial pulse.
