Resumen del Recurso

Pregunta 1

Pregunta
What does the Nervous System enable humans to do?
Respuesta
  • React to their surroundings and to coordinate their behaviour
  • Alert them to pain and when to make reflex actions

Pregunta 2

Pregunta
Information from [blank_start]receptors[blank_end] passes along cells ([blank_start]neurones[blank_end]) as impulses to the central nervous system (the [blank_start]brain[blank_end] or [blank_start]spinal cord[blank_end]). The brain coordinates the [blank_start]response[blank_end].
Respuesta
  • receptors
  • neurones
  • brain
  • spinal cord
  • response

Pregunta 3

Pregunta
The cerebral cortex is concerned with consciousness, co-ordination and unconscious activities.
Respuesta
  • True
  • False

Pregunta 4

Pregunta
The cerebellum is concerned mainly with the coordination of muscular activity.
Respuesta
  • True
  • False

Pregunta 5

Pregunta
The medulla is concerned with unconscious activities such as heartbeat and breathing.
Respuesta
  • True
  • False

Pregunta 6

Pregunta
Scientists have been able to map regions of the brain to paticular fuctions by studying patients with brain damage, [blank_start]electrically stimulating[blank_end] different parts of the brain and using [blank_start]MRI[blank_end] scanning techniques.
Respuesta
  • MRI
  • CAT
  • electrically stimulating
  • artificially stimulating

Pregunta 7

Pregunta
[blank_start]Reflex[blank_end] actions are [blank_start]automatic[blank_end] and rapid. They often involve [blank_start]sensory[blank_end], [blank_start]relay[blank_end] and [blank_start]motor[blank_end] neurones.
Respuesta
  • Reflex
  • Relay
  • automatic
  • quick
  • unconscious
  • sensory
  • impulse
  • relay
  • reflex
  • pain
  • motor
  • movement

Pregunta 8

Pregunta
In a simple reflex action such as pain-withdrawal reflex: (step 1)
Respuesta
  • impulses from a receptor pass along a sensory neurone to the CNS
  • impulses from an stimulus pass along pain neurones to the CNS

Pregunta 9

Pregunta
Reflex actions step 2:
Respuesta
  • at a synapse between a sensory neurone and a relay neurone in the CNS, a chemical is released that causes an impulse to be sent along a relay neurone
  • at a synapse between a relay neurone and a motor neurone in the CNS, chemical energyl is released that causes an impulse to be sent along a motor neurone

Pregunta 10

Pregunta
Simple reflex action part 3:
Respuesta
  • a chemical is then released at the synapse between a relay neurone an motor neurone in the central nervous system, causing impulses to be sent along a motor neurone to the effector
  • at a synapse between a sensory neurone and a relay neurone in the CNS, a chemical is released that causes an impulse to be sent along a relay neurone

Pregunta 11

Pregunta
Simple reflex action part 4:
Respuesta
  • the effector is either a muscle or a gland: a muscle responds by contracting and a gland responds by secreting chemical substances
  • the effector is either a nerve or a gland: a nerve responds by sending impulses to the brain and a gland responds by secreting chemical substances

Pregunta 12

Pregunta
Effector include muscles and glands.
Respuesta
  • Stimulus
  • Receptor
  • Co-ordinator
  • Effector
  • Response
