What are the different types of nerves in the human body?
, which contains two divisions, has a nervous system of the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of a brain that is connected to the spinal cord, serves as a primary control and integration center for incoming information. Here are relevant answers to incoming information about sensory and motor nerve. PNS has sensory receptors for senses including sight and hearing. These structures communicate with the brain through the cranial nerves in the human body and the spinal cord with the spinal cord. The human brain comes 12 cranial nerves, which are arranged in pairs that transmit sensory information such as vision, touch and hearing. This is possible, for example, sensory receptors in the head, such as optical nerves that transmit nerve signals from the eye to the brain. Face movements are controlled and adjusted by the third skull, which are referred to as the nerves of the face, and the fourth cranial nerves are important for the movement of the eyeball, referred to as trochlear nerves.
operates automatically without voluntary action, autonomous division helps maintain the homeostasis of the system through regulatory mechanisms, such as heart rate control and maintaining constant body temperature temperature. The receptors based in organs transport information through afferent nerves in the human body to the CNS for interpretation. The decision is then transmitted to eperential nerves to targeted glands and muscles. The eperential part of the autonomic nervous system is further divided into parasympathetic asympathic nervous systems. Both types of nerves in the human body are found in organs, each of which has effects that reverse the effect of the other.
Spinal nerves - a total of 31 pairs - stems from the spinal cord, which are named after the area of the vertebral column from which they arise. Eight pairs of uterine nerves, 12 pairs of nerves from the thoracic region and five pairs of lumbar nerves come from the column. From the area of the coccygeal area of the spinal cordY also occurs a few nerves. Each backbone nerve is divided into several branches: autonomous, dorsal and ventral. Nerves in the human body from the spine can also form a plexus referring to a grouping of various backbone nerves.
