Verified and Updated Questions and
Answers (100% Correct Answers)
The brain is continuous with the spinal cord near a hole in the base of the skull
called
Answer: the foramen magnum.
The part of the brain that is directly continuous with the spinal cord is called
Answer: the brainstem
The brainstem has three parts
Answer: from rostral to caudal: the midbrain, the pons and the medulla
The term rostral means
Answer: anterior, superior, or towards the front of the brain
The term caudal
Answer: means towards the back of the brain or towards the tail of the spinal cord.
Dorsal means
Answer: towards the upper surface; ventral means towards the under surface.
There are five phylogenetic subdivisions of the adult brain - from rostral to caudal:
Answer: the telencephalon, diencephalon, mesencephalon, metencephalon and
myelencephalon
The telencephalon is essentially the
Answer: hemispheres of the brain (the most recently evolved areas).
The outer rim of the telencephalon, the cortex, consists of
Answer: neuron cell bodies that carry out numerous functions, including higher
intellectual activities, such as reasoning and planning and judgement
The cortex allows us to carry out
Answer: volitional actions (thoughts and movement) and to have subjective
perceptions of ourselves and the world around us.

The diencephalon consists of
Answer: paired nuclear complexes that lie deep in the hemispheres of the brain,
including the globus pallidus, thalamus and hypothalamus.
The globus pallidus is involved in motor function and is part of a circuit that is
disrupted in
Answer: Parkinson's disease
The thalamus is made up of
Answer: multiple individual collections of cell bodies, or nuclei, the main purpose
of which is to receive sensory information (e.g., vision, touch, sound) and then relay
that information to the cortex of the brain
Virtually all of the sensory information that we perceive must go through the
Answer: thalamus before it reaches the cortex (so it really is an anteroom of sorts).
Like the thalamus, the hypothalamus
also consists of
Answer: collections or groups of nuclei that have individual functions.
As a whole, the hypothalamus is important for maintaining the
Answer: homeostasis of the body.
Examples of hypothalamic function include
Answer: the regulation of temperature, food &
water intake and sleep wake cycles.
The mesencephalon, or midbrain, is the most
Answer: rostral part of the brainstem.
Some of the most important functions of the mesencephalon, or midbrain, are
Answer: the nuclei that innervate extraocular muscles for eye movement and
intraocular muscles for adjustment of pupillary size in different intensities of light.
The metencephalon consists of two parts
Answer: the pons and the cerebellum
The cerebellum is the part of the brain involved in
Answer: coordinating movement (damage to the cerebellum
