GRCC BI 121 #4

Nerves Test # 4

QuestionAnswer
Function of nervous system Transmission of electrical signals (nervous impulse) and integration within the environment
Integration what to do in an environment or with stimulation
This function allows us to figure out what to do with a sensory stimulation Integration which is a function of the nervous system.
Transmission of electrical signals Nervous impulse
Nervous system components Neurons (nerve cells), neuroglia, synapses, neurotransmitters, CNS, PNS
Nervous system component: Neuron AKA Nerve Cell; Produces, transmits and interprets nervous impulses.
A nerve cell that produces, transmits and interprets nervous impulses Nerve cell- a Nervous System Component
Nervous system components: Neuroglia Supportive cells around a neuron.
A supportive cell around a neuron Neuroglia - Nervous system components
Neuroglia- a nervous system component The function of this type of cell nourishes, insulates and provides structural support
Nervous system components:Synapses gaps between adjoining neurons
Nervous system components: Neurotransmitters chemicals that carry electrical across the synapse
Name the chemicals that carry an electrical charge across the synapse. Neurotransmitters- a nervous system component
Nervous system Component: central nervous system Brain and spinal cord
Nervous system component: Peripheral nervous system cranial and spinal nerves
what makes up the cranial & spinal nerves? Peripheral Nervous System- a nervous system component.
What makes up the brain and spinal cord central nervous system- a nervous system component
What makes up the general function and transmission of the nervous system Sensory, Integration and motor
Sensory Receives stimuli from environment via sensory receptors in PNS
Sensory receptors recieves info from internal/external environment, converted sensory impulses, which are transmitted over pns to CNS
stimuli converted to nervous impulse and transferred from __________ to CNS for processing PNS
CNS stimuli converted to nervous impulse and transferred from PNS to ________ for processing
Integration CNS processes all sensory signals and creates sensations, memory or thoughts or actions.
sensory receptors- _____________- transmitted over PNS - transmitted to CNS- Integrated into a fx -CNS carries out response converts to stimuli nerve impulses
sensory receptors-converts to stimuli nerve impulses- _________ - transmitted to CNS- Integrated into a fx -CNS carries out response transmitted over PNS
sensory receptors-converts to stimuli nerve impulses- transmitted over PNS - transmitted to CNS- ___________ -CNS carries out response Integrated into a fx
_____________-converts to stimuli nerve impulses- transmitted over PNS - transmitted to CNS- Integrated into a fx -CNS carries out response sensory receptors
sensory receptors-converts to stimuli nerve impulses- transmitted over PNS - transmitted to CNS- Integrated into a fx -_____________ CNS carries out response
This happens after the nervous impulse and transforms to CNS for processing integration
name the term where the CNS processes the nervous impulse creating sensations, memory, thoughts or actions Integration- function and transmission in the nervous system.
Motor CNS sends impulse to stimulate movements in effectors outside of nervous system
Nervous system divisions CNS & PNS
CNS An integrative and process center processing of info.
PNS Communication line between body and CNS
Brain and spinal cord CNS
Cranial and spinal nerves PNS
Autonomic nervous system Involuntary impulses that conducts organs (i.e. cardio, smooth muscles and glands)
somatic nervous system Voluntary impulses that moves skeletal muscles.
Sympathetic homeostatic response Positive feedback, which is movement away from set point (i.e. inc temp, uterine contractions)
Parasympathetic homeostatic response Negative feedback, which is movement back towards the set point.
