Week 2 (parts 1 and 2) Flashcards
(56 cards)
what makes up the CNS
brain + spinal cord
what forms the CNS
collection of bundles of axons (nerve cells) and clusters of nerve cell bodies
what is a ganglion
collection of cell bodies
what is a Fasciculus
Cluster of axons forming a recognisable bundle
what is the Funiculus
Bundle of Axons forming a raised bump on the surface of the CNS (especially in the spinal cord
what is a tract
cluster of axons with similar functions
what is the nucleus
cluster of cell bodies with similar functions
which 4 large sections can the brain be divided in
- Brainstem
- Diencephalon
- Cerebellum
- Cerebral Hemispheres or Cerebrum
what does the brainstem link
cerebrum and the spinal cord
what does the brainstem comprise of
Medulla, midbrain and the pons
what functions does the brainstem control
breathing, heart rate and level of consciousness
what is the Diencephalon composed of
Thalamus, Hypothalamus and Epithalamus
what does the Diencephalon play a role in
the intergration of sensory information and the interpretation of pain (some role with hormone release)
what is the cerebellum involved in
maintaining balance and control
what matter is the Cerebrum made out of
Grey Matter, deeper groups of white matter
what are sulci
grooves in the cerebral cortex (separate the gyri)
what are the lobes of the brain
Frontal, Parietal, Occipital, Temporal
where is the frontal lobe located and what is it responsible for
at the front, its responsible some aspects of movement, behaviour, emotion and higher executive function, expressive speech
where is the Parietal lobe located and what is it responsible for
Behind the frontal lobe, its responsible for language, sensation, perception of space
where is the occipital lobe located and what is it responsible for
located at the back, responsible for vision
where is the temporal lobe located and what is it responsible for
located at the sides, responsible for hearing, expressive speech and memory
what is the primary motor cortex responsible for
actual execution of movement
what is the premotor cortex responsible for
preparation of sensory triggered movement and guiding complete behavioural acts
what is the role of the Supplementary motor area
Involved in preparation of self-initiated movement
