Brain structure & Nervous system Flashcards
1
Q
CNS
Epydemal cells
A
Has cerebrospinal fluid (CSF) homeostasis, brain metabolism, and the clearance of waste from the brain. Barrier between compartments
2
Q
CNS
Astrocytes
A
Regulate blood flow, but also transfer mitochondria to neurons, and supply the building blocks of neurotransmitters, which fuel neuronal metabolism take up K+
3
Q
Microglia
A
- Immune cells of the brain (phagocytes & debris of cell)
- secrete neurotrophic factors
- Helps formation of blood barriers
- Provides substrates for ATP production
4
Q
CNS
Oligodendrocytes
A
Myelin sheath
5
Q
Function of
Cerebellum
A
- Involved in movement coodination and posture
- Rate, range, and direction of movement visual, auditory, motor and vestibular
6
Q
Dicephalon
A
- Involved in regulation of the autonomic and endoctrine systems
- Contains Thalymus, Subthalymus, Hypothalymus Epithalymus
7
Q
Brainsteam
A
Involved in sensory motor relays and vital autonomic funtions
8
Q
Spinal cord
A
Relays information from body to brain
9
Q
Cerebral hemisphere
A
Responsible for processing and memory
10
Q
Cerebrum
A
- Divided into left right hemispheres joined by white matter (corpus callosum) large neural axon
- Gray matter involved in abstract resoning and language
11
Q
Frontal lobe
A
- Primary motor cortex (prostierior) for movement & memory
- Premotor for planning movements
- Has Broca’s area and motor cortex
12
Q
Parietal lobe
A
- Somatosensory cortex for auditory and visual heat and pain response to sensory neurones
13
Q
Occupital lobe
A
- Has visual cortex processing images to the brain
14
Q
Temporal lobe
A
- Understanding language in Wernicke’s area
- Auditory cortex is where information is recieved
15
Q
Thalamus
A
- Relays sensory information
- Thalamatic nucleus sends information and receives from sensory cortex
