(134 cards)
The Frontal lobe is responsible for
Judgement, problem solving, creativity, logic, understanding consequences, Emotions,
Memory and learning
Brocas area - Non-fluent expressive aphasia
Motor cortex
Parietal lobe
Object recognition, sense of taste
Somatosensory cortex
Occipital lobe
Visual cortex
Temporal lobe
Hearing, smell, memory
(L) hemisphere - wernikes area, fluent, receptive aphsia
Hippocampus
Short to long term memory
Reticular activating system
Regulates alertness,
Deep sleep, drowsy, low alert, high alert
Anterior spinal artery
Supplies middle medulla including ant spinal cord
Posterior inferior cerebellar artery
Supplies cerebellum
Vertebral artery
supplies the post part of the circle of willis
Ascending pathways are also called and carry which information?
Afferent pathways - carry sensory information to the brain
Decending pathways are also called what and carry which information?
Efferent pathways - control motor function and muscle tone,
The Dorsal column medial lemniscal tract carries which information on which side?
Crosses in the medulla, travels ipsilaterally
Proprioception, vibration, tactile discrimination
Separated into fasiculus cunatus: upper extremity
Fasciculus gracilis: lower extremity
The spinothalamic tract carries which information on which side?
Pain and temperature (lateral) Crude touch (anterior) on the contralateral side. Decussation at the level.
The corticospinal tract is responsible for what?
Voluntary motor control
Vestibulospinal tract is responsible for what?
Muscle tone, antigravity muscles, Postural reflexes, head on trunk stabilisation, VOR
Rubrospinal tract
Proximal limb flexors - causes flexion in the upper extremities.
Reticulospinal tract
Excitatory to extensors and axial muscles (medial) inhibitory to extensors (lateral)
What is usually the cause of decreased DTR? and Increased?
Peripheral issue for decreased and a central issue for exaggerated
