Name three parts of a neuron
cell body, axons, dendrites
1 of 34
What are dendrites?
Branching structures that receive information from other neurons
2 of 34
What are axons?
Branching structures that carry information to other neurons and transmits and action potential
3 of 34
What is a synapse?
The small gap between the neurons in which neurotransmitters are released, permitting signalling between neurons
4 of 34
What is an Action Potential?
A sudden change (depolarisation and depolarisation) in the electrical properties of the neurone membrane in an axon
5 of 34
What are neurotransmitters?
Chemical signals that are released by one neurone and affect the properties of other neurons
6 of 34
What is myelin?
A fatty substance that is deposited around the axon of some neurons that speeds conduction
7 of 34
What is gray matter?
Matter consisting primarily of neuronal cell bodies
8 of 34
What is white matter?
Tissue of the nervous system consisting primarily of axons and support cells (glia)
9 of 34
What are glia?
support cells of the nervous system involved in tissue repair and i the formation of myelin
10 of 34
What is the corpus callosum?
A large white matter tract that connects the two hemispheres
11 of 34
Which ventricle lies in the brain stem?
Fourth ventricle
12 of 34
Which ventricles are found in each hemisphere?
Lateral ventricles
13 of 34
Which ventricle lies centrally around the subcortical structures?
Third ventricle
14 of 34
Name three parts of the basal ganglia
Putamen, Caudate nucleus, globus pallidus
15 of 34
Name three structures in the diencephalon
Thalamus, Hypothalamus, Mamillary bodies
16 of 34
Name three structures of the hindbrain
Cerebellum, Pons, Medulla oblongata
17 of 34
Name two structures of the midbrain
Superior and inferior colliculi, substantia nigra
18 of 34
Which two areas make up the forebrain?
Diencephalon and cerebrum (telencephalon)
19 of 34
What is another word for cerebrum?
20 of 34
What three areas of the cerebrum?
Cerebral cortex, limbic system, basal ganglia
21 of 34
Name the three parts of the limbic system
Amygdala, Hippocampus, Cingulate cortex
22 of 34
What are the basal ganglia?
Subcortical gray matter. Large rounded masses in each hemisphere. Surround thalamus. Involved in motor control and skill learning
23 of 34
What are two diseases of the basal ganglia?
Parkinson's (hypokinetic) and Huntingdon's disease (hyperkinetic)
24 of 34
What is the limbic system?
A region of subcortex involved in relating the organism to its present and past environment. It detects and expresses emotional responses
25 of 34
Which lobe are the amygdala and hippocampi (limbic) found in?
Temporal lobe
26 of 34
Name two small structures that are visible from the ventral surface
Mamillary bodies and olfactory bulbs
27 of 34
What are the mamillary bodies (diencephalon/limbic)?
Two small, round protrusions that have been implicated in memory.
28 of 34
Which lobe do the olfactory bulbs (limbic) lie under?
Frontal lobe
29 of 34
What is the thalamus (diencephalon)?
A major subcortical relay centre and sensory processing station between all sensory organs (except smell) and the cortex
30 of 34
What is the hypothalamus (diencephalon)?
A variety of nuclei that are specialised for different functions, primarily concerned with the body and its regulation e.g. body temp, hunger, thirst, endocrine regulation
31 of 34
What structures are easily visible from the ventral surface?
Medulla, pons, midbrain, mamillary bodies, hypothalamus, optic: tracts, chiasm, nerves, olfactory bulbs
32 of 34
What lies at the posterior end of the thalamus?
Lateral geniculate nucleus (visual) and the medial geniculate nucleus (auditory)
33 of 34
What structures are visible from a coronal section through the amygdala?
2 amygdalas, hypothalmus, thalamus, ventricle (3rd?), lateral ventricle, and basal ganglia (caudate nucleus, putamen, globus pallidus)
