Flashcards in O15 Neurology - FINAL EXAM Deck (24):
All behavior is...
Who are Broca and Wernicke?
Anatomists, doctors and scientists who noticed that when a specific area of the brain is injured, specific deficits/behaviors resulted.
T/F: Behavioral symptomology & lesion sites are predictable.
What is neuroscience and what are it's two components?
It focuses on the brain and central nervous system. It is neuroanatomy and neurophysiology.
What is the CNS made up of?
What is the peripheral nervous system (PNS)?
Nerves that exit the cranium and spinal cord.
What will damage to the PNS result in?
How many cranial nerves are there?
12 total (right & left pairs)
How many spinal nerves are there?
31 total (right and left pairs)
What do the cranial nerves provide for?
the head, face, and neck
What are the 12 cranial nerves?
CN I Olfactory
CN II Optic
CN III Occulomotor
CN IV Trochlear
CN V Trigeminal
CN VI Abduceans
CN VII Facial
CN VIII Accoustic/Vestibulocochlear
CN IX Glossopharyngeal
CN X Vagus*
CN XI Accessory
CN XII Hypoglossal
What are the four functions of the nervous system?
Sensor - register sensory information (touch, taste, smell, vision, hearing)
Motor - Movement
Integrator - interprets & processes incoming information
Regulator - brainstem function that regulates temperature, blood pressure, alertness, readiness, & muscle tone.
What are the two functional divisions of the Peripheral Nervous System?
1. Autonomic Nervous System (ANS): Does automatic things that we are unconscious of, such as breathing.
2. Somatic Nervous System (SNS): Voluntary & deliberate (muscles, speaking, hearing)
What are areas 1, 2, & 3?
Somatosensory Cortex - primary sensory
What is area 4?
Primary Motor Cortex
What are areas 5, 7, & 40?
Association for primary sensory (1, 2, & 3)
What is area 6?
Premotor cortex (association for area 4 primary motor)
What are areas 9, 10, & 11?
Prefrontal cortex - thinking, reasoning, executive function, problem solving, & social inhibitions.
What is area 44?
Broca's area - SPEECH (motor planning and executing of speech)
What is area 22?
Wernicke's area - LANGUAGE
What is areas 41 and 42?
Primary auditory cortex
What is area 17?
What are areas 18 and 19?
Association for primary visual
19 - following movements
18 - interpretation
