The nervous system enables humans to react to their surroundings and to coordinate their behaviour. The endocrine system secretes hormones into the bloodstream from glands throughout the body.
What are the three different types of neurone?
Sensory, reflex and motor neurones
Sensory, relay and motor neurones
Sensory, relay and effector neurones
Which type of neurone is connected to muscles or glands?
Which system in the body releases hormones?
What moves across a synapse?
Chemical transmitter molecules
What makes up the central nervous system (CNS)?
The spinal cord and all neurones in the body
The brain and all the neurones in the body
The brain and spinal cord
Which of the following represents the order during a nervous response?
Receptor → stimulus → coordinator → effector → response
Response → receptor → coordinator → effector → stimulus
Stimulus → receptor → coordinator → effector → response
Why do hormones work over a long period of time?
They take a long time to reach the target organ
Once they are released they stay forever
They have an effect until their action is completed and they are broken down
What type of neurone transmits electrical signals within the central nervous system?
How does the pituitary gland affect thyroxine levels? - Higher
By releasing thyroxine from the adrenal gland
By releasing TSH
By breaking it down as it passes through the gland in the blood
Which of these is not an example of negative feedback? - Higher
Regulating blood glucose
Oestrogen triggering the release of more FSH and LH
Maintaining body temperature
