Chapter 3 Cells In Nervous System Notes Pdf Chemical Synapse Synapses are the sites of communication between neurons most synapses in the vertebrate nervous system are chemical, although electrical synapses and mixed (both chemical and electrical) synapses have also been identified at a synapse, the sending neuron is called the presynaptic cell and the receiving neuron is called the postsynaptic cell. Chapter 3 notes the cells in the nervous system fall into two major categories glia neurons neurons: are individual cells in the nervous system that receive, integrate, and transmit information. gila: are cells found throughout the nervous system that provide various types of support for neurons.
Chapter 3 Structure Of The Nervous System Descargar Gratis Pdf Neural communication: insulation and information transfer myelin sheath – speeds up transmission terminal button – end of axon; secretes neurotransmitters neurotransmitters – chemical messengers synapse – point at which neurons interconnect. When the stimulus is weak, the synapse acts as a gap which the impulse cannot cross and the stimulus is ‘filtered out’ due to insufficient secretion of neurotransmitters. • somatic nervous system: conveys info between cns and the body, controlling and coordinating voluntary movement • automatic nervous system: controls involuntary actions of our internal organs, works with limbic system to regulate emotion • sympathetic nervous system: engaged during crisis or after actions requiring fight or flight. Psy exam 3 study guide an overview of all the material learned before exam #3.

(b) in a chemical synapse, a neuron uses a neurotransmitter to c mmunicate with a target cell. when an action potential arrives at the end of the axon, the neurotransmitter is released. the neurotransmitter difuses to the target cell and binds to receptors on the target cell’s membrane,.
