In this way, neural communication enables body functions that involve quick, brief actions, such as movement, sensation, and cognition. When the neurotransmitters binds with receptors on the receiving (post-synaptic) cell, a new electrical signal is generated and quickly continues on to its destination. Once the action potential reaches the synaptic terminal, the electrical signal is converted to a chemical signal as neurotransmitters are released into the synaptic cleft. Electrical signals are sent via the generation and propagation of action potentials which move along the membrane of a cell. As discussed in previous chapters, the nervous system utilizes two types of signals – electrical and chemical ( Table 17.1). The nervous system is primarily responsible for rapid communication throughout the body.
There are two major organ systems responsible for providing these communication pathways: the nervous system and the endocrine system. Identify the major organs of the endocrine system and their location in the bodyĬommunication within the human body involves the transmission of signals to control and coordinate actions in an effort to maintain homeostasis.Distinguish similarities and differences between neural and hormonal communication.By the end of this section, you will be able to:
