Question | Answer |
---|---|
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. |
