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
-
