The CNS And PNS (2) Flashcards
Neuroanatomy *
The structure and connectivity of the nervous system
Neurophysiology
How neurons work and communicate
Which aspect of the PNS conveys sensory info to the CNS
Somatic
The sympathetic NS..
Stimulates
The parasympathetic NS..
Inhibits
The forebrain consists of***
The thalamus and hypothalamus ; the cerebral cortex ; the limbic system ; the corpus collosum
The hindbrain consists of..*
The cerebellum ; the pons ; the medulla
The medulla..**
Regulates our cardiovascular systems
Responsible for reflexes (e.g. swallowing, coughing, vomiting..)
Maintaining body balance (controls limbs position in response to gravity)
The pons..**
Integrates info from movements + sensations from facial muscles, tongue, eye and ear
Regulates brain attentiveness levels and in initiating sleep + dreaming
The cerebellum..
Fine control and coordination of balance and movements using info from muscles, joints and tendons (contains many neurons)
How much brain volume does the cortex account for?
80%
How many thin layers does the cerebral cortex consist of?
Up to 6
Thalamus*..
Contains a large number of RELAY centres (conveying nearly ALL the SENSORY info in the cortex)
Hypothalamus..
Controls the autonomic NS and the endocrine system
Organises basic behaviour for survival
The limbic system..
Surrounds the thalamus and lies just underneath the cortex
Amygdala and hippocampus
Has neural links to the hypothalamus and the cortex
