Figure 1 shows three different types of neuron. Use the letters from Figure 1 to
answer the following questions.
SEE PAPER
Which neuron is only found in the brain/visual system/spinal cord?
A
Which neuron carries nerve impulses from the brain/spinal cord to muscles/glands?
C
Which neuron carries nerve impulses between neurons?
A
The adrenal gland is part of the endocrine system that produces adrenaline to help the
body prepare for the fight or flight response.
Using an example of a gland and hormone, outline the function of the endocrine system.
Do not use the adrenal gland/adrenaline as your example.
Possible content:
* the endocrine system helps to regulate the activity of cells and organs in the body
* the endocrine system communicates chemical messages to the organs of the body
* the thyroid gland produces thyroxine, which increases heart rate and metabolic rates
* the pineal gland produces melatonin, which may help regulate the wake-sleep cycle
* the anterior pituitary gland secretes Luteinizing hormone (LH) & Follicle-stimulating hormone (FSH),
which stimulate ovaries to produce oestrogen & progesterone
* the anterior pituitary gland secretes LH & FSH, which stimulate the testes to produce testosterone &
sperm
* the posterior pituitary releases oxytocin, which stimulates the uterus to contract during labour and also
plays a role in bonding
* the pancreas secretes insulin and glucagon, which help regulate blood sugar levels.

Note – the gland and hormone referred to do not need to be related.
Note – simply naming a gland and hormone max 1 mark
