Physiology Exam Retake Flashcards
Broca’s Area
Motor Function and Speech
ie: Inability to form sentences or words
Frontal lobe
Wernicke’s Area
Ability to understand, but cannot formulate proper sentences “word salad”
Temporal lobe
Substantia Nigra
Nucleus in the midbrain and is part of the basal ganglia.
Degeneration of the substantia nigra results in Parkinson’s Disease
Role of the Spleen
- All = TRUE*
Site for immune surveillance and response
Removes debris, foreign matter, toxins, bacteria, viruses, old blood cells
Readily subject to rupture from mechanical trauma
Lymphatics - filtration process
Spleen - helps with filtration process
Graveyard for RBC - important for immune system and RBC recycling
Type 4 Hypersensitivity
Cell Mediated Reaction (transplant - kidney)
What region of the brain is responsible for understanding language, human behaviour, memory and hearing?
Temporal Lobe
Cranial Nerves are associated with the..
Brainstem
A lady is applying make up, but only applies it to the left side of her face. Where is the lesion?
The opposite side of the brain/face she is NOT applying it to.
Right heart failure
Peripheral Congestion
Left = pulmonary congestion
Mast Cells
Associated with Tuberculosis
CD4+
HIV / AIDS
Role of the cerebellum
To maintain muscle tone,
Coordinate muscle movement,
Posture and control
Balance/equilibrium

S1 radiculopathy (compression of the nerves)
Patient is presenting with lack of facial expression, stooped gait and smaller handwriting
Affects the basal ganglia (symptoms of Parkinson’s Disease)
What part of the brain is responsible for joint positioning and placement?
Cerebellum
Brown-Sequard Syndrome
Motor & Vibration/Proprioception - SAME SIDE

Guillan Barre Syndrome
Acute rapidly evolving polyneuropathy that often starts in the distal lower limbs and ascends
Occurs AFTER a series of infections
Absent P Waves on ECG

Mononuclear cells, macrophages, lymphocytess, plasma
What cells will be present after 48 hours during an inflammatory reaction?
Macrophages
Mast Cells
Associated with TB
HIV / AIDS
CD4
