Human Physiology review for different functions of parts of the brain Flashcards
Oldest region of the brain.
Brain stem
Continuous with spinal cord.
Brain stem
First brain structure to evolve.
Brain stem
Responsible for vegetative functions such as cardiovascular, respiratory and digestive functions.
Brain stem
Majority of cranial nerves arise here.
Brain stem
Regulates postural reflexes.
Brain stem.
Responsible for cortical awareness.
Brain stem.
Plays a role in the sleep-wake cycle
Brain stem
Most highly developed in humans.
Cerebrum
Handles higher functions such as thinking, learning, memory, language, motor function.
Cerebrum
Most complex integrating centre in brain.
Cerebrum
Outer layer of the cerebrum.
Cerebral cortex.
Located in the back of the brain and houses the visual cortex.
Occipital lobe.
Houses the auditory cortex.
Temporal lobe.
Houses the somatosensory cortex.
Parietal lobe.
Handles somaesthetic sensations.
Parietal lobe
Proprioceptive input is directed here.
Parietal lobe.
Located behind the central sulcus.
Somatosensory cortex
Voluntary motor activity
Frontal lobe
Elaboration of thought.
Frontal lobe.
Houses the primary motor cortex.
Frontal lobe
Left hemisphere at the junction of the parietal, temporal and occipital lobes.
Wernicke’s
Concerned with language comprehension.
Wernicke’s
Left frontal lobe, close association with motor cortex.
Broca’s
Concerned with speaking ability.
Broca’s
Ring of structures that surround the brain stem and are interconnected by a neuron pathway.
Limbic system
Includes lobes of the cerebral cortex, basal ganglia, thalamus, hypothalamus and hippocampus.
Limbic system.
Which NTs does the limbic system use?
Norepinephrine, Serotonin and dopamine.
Fast track of basic behavioural pattern.
Amygdala
Slow track of basic behavioural pattern (refined and rational thinking)
Pre-frontal cortex
Storage of declarative memories
Hippocampus
Storage of procedural memories
Cerebrocerebellum
LTP prevalent in this area
hippocampus
Balance and eye movement
vestibulocerebellum
enhances muscle tone
spinocerebellum
coordinates skilled movements
spinocerebellum
planning and initiating voluntary activities
cerebrocerebellum
Sensory relay station
Thalamus
Direct attention to stimuli of interest
Thalamus
Capable of crude awareness of sensation
Thalamus
Reinforce voluntary motor activity
Thalamus
Body temperature and food intake
Hypothalamus
Thirst and urine output
Hypothalamus
Anterior pituitary hormone secretion
Hypothalamus
Posterior pituitary hormones
Hypothalamus
Grey matter within white matter core in brain.
Basal ganglia
Inhibits muscle tone
Basal ganglia
selecting and maintaining purposeful motor activity
Basal ganglia
Suppressing unwanted pattern of movement
Basal ganglia
Coordinates slow, sustained contractions
Basal ganglia
Cell bodies of interneurons on which afferent nerves terminate
dorsal horn
Cell bodies of autonomic efferent nerve fibres
Lateral horn
Cell bodies of somatic efferent neurons
Ventral horn
Spinal nerves contain?
dorsal and ventral horns.
