2 hemispheres
Often divided into 5 lobes

20
Q

Frontal lobe

A 
Reasoning 
Planning 
Speech 
Movement 
Emotions 
Problem solving
21
Q

Parietal lobe

A

Movement
Orientation
Recognition
Perception on stimuli

22
Q

Occipital lobe

A

Visual processing

23
Q

Temporal lobe

A

Perception
Recognition of auditory stimuli
Memory
Speech

24
Q

Frontal lobe

A

Responsible for higher cognitive functions: problem solving, memory, language, motivation, social and sexual behaviour

25
Q

What is the prefrontal cortex?

A

The region of the frontal lobe rostral to the premotor cortex.
Associated with formulating plans

26
Q

What lobe plays a role in emotions?

A

Temporal lobe

27
Q

Where is the motor cortex located?

A

In the rear portion of the frontal lobe, just before the central sulcus

28
Q

The names of the two areas the motor cortex is divided into?

A

Primary motor cortex

Motor association cortex

29
Q

Primary motor cortex

A

Executed movement of skeletal muscle

30
Q

Motor association cortex

A

Plans and coordinates movement

31
Q

Where is the visual cortex located?

A

On the inner surfaces of the occipital lobes

32
Q

Two areas of the visual cortex

A

Primary visual cortex

Visual association cortex

33
Q

Cerebellum

A

Associated with regulation and coordination of movement, posture and balance

34
Q

Where is the limbic love located?

A

Dee in the brain and makes up the limbic system

35
Q

The limbic system

A 
Limbic cortex 
Hippocampus 
Amygdala 
Fornix
Mammillary bodies 
Thalamus 
Hypothalamus
36
Q

What does the limbic system do?

A

Area of the brain that regulates emotion and memory

37
Q

What does the limbic system control?

A

Basic emotions and drives

38
Q

Thalamus

A

Located deep in the brain at the top of the brainstem.

Main function is to relay and motor and sensory signals to the cerebral cortex.

39
Q

Hypothalamus location?

A

Sits under than thalamus at the top of the brainstem

40
Q

What does the hypothalamus control?

A

The autonomic nervous system
Centre for emotional response and behaviour
Regulates body temp and food intake
Controls endocrine system

41
Q

Where is the medulla oblongata

A

Merges seamlessly with the spinal cord and creates the base of the brain stem

42
Q

What does the the medulla control?

A 
Vital reflexes: 
Swallowing 
Vomiting
Coughing 
Respiratory system
43
Q

Where is the pons located

A

Rounded brainstem region between the midbrain and the medulla oblongata

44
Q

Main function of the pons

A

To connect the cerebellum to the rest of the brain and to modify the respiratory output of the medulla

45
Q

Inter- neurons

A

Small neurons with short exams that interconnect with other spinal nerurons

Provide spinal integration of sensory and motor signals

46
Q

Motor neurons

A

Large cells, found in ventral horn
