16
Q

location and function of the somatosensory association area

A

location- posterior to the primary somatosensory area
function-determination of shape,texture, orientation, and relations of the parts of the objects

17
Q

location and function of the prefrontal cortex

A

location-anterior part of the frontal lobe
function- personality features, intellect, complex learning abilities, reasoning, planning, initiative, judgement, foresight, recall of information

18
Q

location and function of the visual association area

A

location- occipital lobe
function- recognition and evaluation of the visual perceptions

19
Q

location and function of the auditory association area

A

location-inferior posterior to the primary auditory area
function- recognition of auditory perception

20
Q

location and function of the common integrative area

A

location close to the somatosensory, visual and auditory area
function- receives and integrates sensory impulses and interpretations from different areas

21
Q

location and function of the premotor area

A

location- anterior to primary motor area
function- complex learned motor activity patterns

22
Q

location and function of the Wernicke’s area

A

location- temporal and parietal lobes
function- interprets the meaning of speech by recognising spoken words

23
Q

what surrounds the diencephalon,
what does it consist of,
what does it enclose

A

surrounded by the cerebral hemispheres, superior to the midbrain
consists of the thalamus, hypothalamus, epithalamus
encloses the third ventricle

24
Q

what does the thalamus consist of
what is its role

A

paired oval masses of grey matter with tracts of white matter, 7 major groups of nuclei
role- major relay station for sensory impulses, motor function, autonomic activities, Maintenace of consciousness

25
Q

what does the hypothalamus consist of
what is its role

A

consists of several nuclei arranged in four regions
role- controls and integrates activities of the autonomic nervous system Eg hormones, body temperature, emotional+behavioural patterns

26
Q

what does the epithalamus contain, where is that located and what does it control

A

contains the pineal gland, located in the posterior extremity of the 3rd ventricle
controls- release of melatonin and habenular nuclei

27
Q

location and function of the cerebellum

A

location- posterior and inferior aspect of the cranial cavity
function- evaluate movement, regulates posture and balance

28
Q

what does the cerebellum consist of

A

cortex folded into folia, which contains white matter which contains cerebellar nuclei

29
Q

what are the hemispheres of the cerebellum connected by and what are the lobes of the cerebellum

A

hemispheres are connected by vermis
lobes are, anterior, posterior, flocculo-nodular

30
Q

layers of the cerebellar cortex

A

molecular layer
purkinje cell layer
granular cell layer

31
Q

three main parts of the brainstem

A

midbrain
pons
medulla oblongata

32
Q

what does the midbrain connect
what does the anterior part contain+role
what does the posterior part contain and role

A

connects- 3rd and 4th venticles
anterior part contains- cerebral peduncles which share motor impulses
posterior part contains-superior and inferior colliculi, role visual reflexes Eg getting startled

33
Q

pons-location+contains+made of+two regions

A

location- midbrain and medulla
contains 4th ventricle
made of tracts and nuclei
regions- ventral, dorsal

34
Q

function of the ventral region of pons and components of the dorsal region of pons

A

ventral region- relay station for white matter tracts
dorsal region- ascending sensory and descending motor tracts, cranial nerves nuclei

35
Q

location and what does white matter in the medulla oblongata contain

A

location-between the pons and spinal cord
white matter contains sensory and motor tracts, two pyramids and olives

36
Q

what is the function of the grey matter in the medulla oblongata

A

vital functions Eg cardiovascular centre, respiratory area, reflexes for vomiting, sneezing, coughing
cranial nerves

37
Q

function of the ascending sensory tract and descending motor tract

A

ascending sensory-maintain consciousness
descending motor tract- regulation of resting muscle tone

38
Q

Oh Oh Oh Those Trippy Alien Fruit Vines Generate Visions And Hallucinations.

A

Olfactory
Optic
Oculomotor
Trochlear
Trigeminal
Abducens
Facial
Vestibulocochlear
Glossopharyngeal
Vagus
Accessory
Hypoglossal
