Document Summary
Neural and hormonal systems (chapter 5) contin: how neurons communicate, the axon of one cell fused with the dendrites of another. i. ii. i. Sir charles sherrington noticed how long the neural impulses were traveling to a neural pathway. He later stated that the meeting point between neurons was the synapse: the tiny gap at this junction is called the synaptic gap, dendrites and axons do not quite touch. Neurotransmitters are chemical messengers that cross the synaptic gap. Agonists may: antagonists decrease a neurotransmitter"s action by blocking production increase the production or release of neurotransmitters. or release. i. Example : botulin, a poison that can form in improperly canned food, causes paralysis by blocking ach release. Neural communication: hen one lives, one has to take in information from the world and one"s body tissues, to make decisions and to send back information and orders to the body"s tissues.
