21
Q

Hormones

A

chemical messages that act on the brain, manufactured by the endocrine glands

22
Q

Resting potential

A

neuron is polarised with a negative charge inside the cell membrane and a positive charge outside

23
Q

Action impulse

A

when the neuron fires

24
Q

graded potential

A

the spreading voltages that occur as one neutron is excited by other neutrons.

25
Q

The two cerebral hemispheres are connected by the

A

corpus callosum

26
Q

The foundation of human thought and language is found in one of the functions of:

A

cerebral cortex

27
Q

Stimulation of the septal area of the limbic system

A

is powerfully reinforcing

28
Q

The term ‘lateralised’ refers to the fact that

A

cortical functions are localised to one or the other side of the brain

29
Q

Neurons send signals by

A

Neurons communicate with one another at the synapse through a process where a chemical message alters the electrical charge of the next neuro

30
Q

People with excessive levels of dopamine may experience

A

abnormally high levels in certain areas of the brain have been linked to schizophrenia

31
Q

The ability to feel a wedding ring on your finger and to see the cat running through a room requires a normally functioning _______ lobe

A

parietal

32
Q

parietal Lobes

A

The parietal lobes control various functions such as sense of touch, detecting movement in the environment, and experiencing one’s own body

33
Q

Frontal lobe

A

Abstract thinking, planning, social skills

34
Q

Parietal lobe

A

touch, spatial orientation, non verbal thinking

35
Q

Occiptal lobe

A

Vision

36
Q

wernickes area

A

Speech comprehension

37
Q

Temporal lobe

A

Language hearing visual pattern recognition.

38
Q

Broca’s area

A

Speech production

39
Q

cerebral cortex includes

A

primary areas with usually process raw sensory data

40
Q

Cerebral lateralisation

A

psychological functions are processed primarily by one hemisphere

41
Q

Left hemisphere is

A

more verbal and analytical

42
Q

Right hemisphere

A

non-linguistic functions

43
Q

Interneurons

A

connect neutrons with one another

44
Q

CNS

A

Central nervous sustem

45
Q

PNS

A

peripheral nervous system

46
Q

Somatic nervous system

A

Sensory neutrons that carry sensory information to the brain and motor newtons that direct the action of skeletal muscles

47
Q

Autonomic nervous system

A

Controls basic life processes such as the beating of the heart.

48
Q

Sympathetic nervous system

A

activated in response to threats or emotional arousal

49
Q

Parasypathetic nervous system

A

involved in routine activities such as maintaining the body’s energy resources and restoring the stetted to an even keel after a sympathetic activation

50
Q

Inhibitory neurotransmitters

A

hyperpolarise the post-synaptic neuron
Inhibitory neurotransmitters inhibit the firing of a neuron; that is, they reduce the likelihood that the post- synaptic neuron will fire.
