The ____ ____ separates the two hemispheres of the cerebellum

A

falx cerebelli

32
Q

There is one ____ ventricle in each hemisphere of the cerebrum

A

lateral

33
Q

_____ ____ is a clear colourless liquid composed of primarily water that protects the brain and spinal cord from chemical and physical injuries

A

Cerebrospinal fluid

34
Q

The ____ ventricle is a narrow slit-like cavity along the midline superior to the hypothalamus and between the right and left halves of the thalamus

A

third

35
Q

The ____ ventricle lies between the brain stem and the cerebellum

A

fourth

36
Q

Name the structures of the forebrain

A 
Cortex
corpus callosum
Parieto occipital sulcus
Calcarine sulcus
primary visual cortex
Basal Ganglia
Diencephalon (Thalamus, hypothalamus, pituitary, third ventricle)
37
Q

Name the structures of the midbrain

A 
The superior colliculus
The inferior colliculus
Cerebral aqueduct
Cerebral peduncles
substantia nigra
38
Q

What are the functions of the midbrain structures?

A

S - reflex response to sight
I - reflex response to sound
The cerebral peduncles convey corticospinal and corticopontine fibres. White matter.
The cerebral aqueduct conveys cerebrospinal fluid from the third ventricle to the fourth ventricle.

39
Q

What are the functions of the hindbrain structures?

A

Cerebellum controls balance and coordinates movement.
Pons and medulla contain corticospinal fibres, nuclei of cranial nerves.
Medulla is involved in control of the CV and respiratory systems.

40
Q

What is the function of the cingulate gyrus?

A

Involved in the limbic system, and the emotions.

41
Q

Describe the position of the central and peripheral primary visual cortex relative to one another.

A

of the central and peripheral primary visual cortex’s relative to one another.
The primary visual cortex is on the occipital pole of the brain. Central vision is focused around the occipital pole, and peripheral vision is housed deeper into the occipital lobe.

42
Q

A

Wernickes area (comprehension)
Broca’s area (motor control of larnyx and tongue for speech production)
Exener’s area (motor control of hands for writing)
Supramarginal and angular gyri (reading and writing abilities respectively)
