The part of the mammalian brain that has shown maximum relative growth is the:
1. the cerebellum
2. the cerebrum
3. the diencephalon
4. corpora quadrigemina
Interneurons:
1. are seen only in the central nervous system
2. are seen only in the peripheral nervous system
3. are always motor in nature
4. occur in the central nervous system and link afferent and efferent neurons
Neurotransmitters:
1. are chemical signals.
2. are broken down slowly after they are released.
3. occur in gap junctions.
4. are released by the postsynaptic cell.
Impulses are carried towards the soma of the neuron by:
1. intermediate filaments
2. axon
3. neurotransmitter
4. dendrites
Identify the neurotransmitter that is correctly matched with the amino acid it is derived from:
1. serotonin derived from phenylalanine
2. norepinephrine derived from glycine
3. acetylcholine derived from cysteine
4. epinephrine derived from tyrosine
The four major lobes of the cerebrum are called as:
1. dorsal, ventral, lateral and medial
2. parietal, frontal, dorsal, occipital
3. motor, sensory, associative and integrative
4. frontal, parietal, temporal and occipital
Corpus callosum:
1. is a part of the ventricular system.
2. divides the frontal lobe from the parietal lobe.
3. connects the right and left cerebral hemispheres.
4. is an extension of the diencephalon.
Which of the following has most of the cerebrospinal fluid at any instant?
1. dural sinuses
2. pia mater
3. subarachnoid space
4. epidural space
Forebrain in early developmental stage is called:
1. prosencephalon
2. diencephalon
3. telencephalon
4. rhombencephalon
Located in the lower portion of the frontal lobe, the Broca's area is primarily concerned with:
1. visual reflexes
2. motor speech
3. neural hearing
4. sensory impulses
