Q

Describe the neuronal process bw neurones

A

The signal (ball) flies over the synaptic gap (field) to another neuron (player) and the process repeats itself. The dendrite receives the chemical signal or neurotransmitter > excites the neuron > sodium ions enter the neuron and charge it > an electric current travels through the axon > and the terminal branches fire off the signal over the synaptic gap to the next neuron.

40
Q

Your hippocampus processes

A

feelings of fear and anger

42
Q

Your pituitary gland is a master gland that helps regulate

A

the release of hormones

43
Q

Your cerebral cortex is made up of four lobes

A

Frontal, Temporal, Parietal and Occipital

44
Q

The frontal lobe of your brain helps to

A

peak, coordinate your movements and is also involved when you plan

45
Q

The temporal lobe of your brain

A

processes information about what you hear

46
Q

The parietal lobe of your brain

A

processes information about what you touch

47
Q

The occipital lobe of your brain processes

A

information about what you see

48
Q

This kind of impairment known as Broca’s aphasia is

A

stroke affecting the frontal lobe of the brain that affects ability to talk

49
Q

What can playing a musical instrument do?

A

It can increase the size of your temporal lobe.

50
Q

What happens when someone has a stroke?

A

The blood doesn’t reach part of their brain.

51
Q

Which of the following can help people with Broca’s aphasia recover their communication ability?

Treatment, rehabilitation, and time.

52
Q

The hormones of your endocrine system help to regulate

A

energy levels, growth, emotions and ability to reproduce

53
Q

Hormones are chemicals that your body produces to tell your cells

A

how to behave

54
Q

The thyroid gland

A

regulates your metabolism, or how fast your body uses energy

55
Q

pancreas regulates

A

how much energy your body gets

56
Q

Your pancreas produces

A

insulin, the hormone that helps your body absorb sugar in your bloodstream to give it energy

57
Q

Difficulties with any of these glands can

A

affect moods and the choices we make

58
Q

adrenal glands (on the top of kidneys)

A

pump out adrenaline hormones when you’re faced with stress or excited

59
Q

Male sex glands produce

A

testosterone

60
Q

Female sex glands produce

A

estrogen

61
Q

The pituitary gland in your brain is called the ‘master gland’ because

A

it secretes hormones that trigger your other glands. It regulates the amount of hormones released by your thyroid, adrenal glands, pancreas and sex glands. It’s the command center that controls your body’s growth, and signals your ovaries or testes to make testosterone or estrogen.
