Synthesis of the neurotransmitter. This can take place in the cell body, in the axon, or in the axon terminal.Eg. acetylcholine; Storage of the neurotransmitter in vesicles in the axon terminal.
The nervous system of vertebrates (including humans) is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). [16] The CNS is the major division, and consists of the brain and the spinal cord. [16] The spinal canal contains the spinal cord, while the cranial cavity contains the brain.
The central nervous system (CNS) controls most of the functions of the body and mind. It comprises the brain, spinal cord and the nerve fibers that branch off to all parts of the body. The CNS viral diseases are caused by viruses that attack the CNS. Existing and emerging viral CNS infections are major sources of human morbidity and mortality.
Researchers prove that in the developing CNS, Nav1.2 is initially expressed at all forming nodes of Ranvier. [11] Upon maturation, nodal Nav1.2 is down-regulated and replaced by Nav1.6. Nav1.2 is also expressed during PNS node formation, which suggests that the switching of Nav-channel subtypes is a general phenomenon in the CNS and PNS.
Neuroendocrine neurons were discovered in the peripheral nervous system, regulating, for instance, digestion. The cells in the adrenal medulla that release adrenaline and noradrenaline proved to have properties between endocrine cells and neurons, and proved to be outstanding model systems for instance for the study of the molecular mechanisms ...
Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.
There are two parts of the nervous system: the central nervous system (CNS) and the peripheral nervous system (PNS). General body functions are supervised by the central nervous system (CNS), which includes the brain and spinal cord. The PNS delivers motor signals to control body activities and receives sensory data from the CNS.
