M11 Brain Flashcards
cortical site involved with controlling movements of the body
primary motor cortex (precentural gyrus)
controls facial neurons, speech and language comprehension. Located on the Left frontal lobe
Broca’s Area
results in the ability to comprehend speech but the decreased motor ability (or inability) to speak and form words
Broca’s Aphasia
responsible for hearing
primary auditory cortex
interprets the sense of smell once it reaches the cortex
primary olfactory cortex
language comprehension. Located on the left temporal lobe
wernicke’s area
language comprehension is inhibited. words and sentences are not clearly understood and sentence formation may be inhibited or non-sensical
wernicke’s aphasia
Lobes and Structures of the brain Labeling
A. Central Sulcus B. Frontal Lobe C. Sylvian/Lateral Fissure D. Temporal Lobe E. Transverse Fissure F. Occipital Lobe G. Parietal Lobe
gathers information about changes occuring within and around the body
sensory
____ receptors, at the ends of ____ nerves, send signals to ____
Sensory receptors, at the ends of peripheral nerves, send signals to CNS
______information is “brought together” interpreted, to create sensations, create thoughts, add to memory, make decisions, ect
Integrative
sending of signals to muscles and/or glands to elicit a response
motor
the three general functions of the nervous system (in order) are:
sensory, integrative, and motor
The central nervous system is composed of:
These neurons ____
the brain and the spinal cord.
cannot regenerate if damaged
the peripheral nervous system is made up of:
these neurons _____
peripheral nervous that connect the CNS to the rest of the body
can regenerate if damaged
There are ___ peripheral nerves
33
there are _ cranial nerves
12
the gaining (taking in) information from the outside world- hot, cold, pressure, pain, 5 senses
sensory
the movement/muscle control portion of the nerve
motor
12 pairs of cranial nerves diagram
I. Olfactory II Optic III oculomotor IV trochelar V trigeminal VI abducens VII facial VIII vestibulecochlear IX glossopharyngeal X Vagus XI Spinal Accessory XII Hypoglossal
___ of the nerves are very important for speech and swallowing
6
Controls the ability to smell
I. olfacory
controls the ability to see/vision
II. Optic
visual convergence and accommodation /controls muscles of the eye
III oculormotor
rotates eye down and out /superior oblique muscle
IV trochlear
sensations to eye, nose, and face: meninges; muscles of mastication and tongue/ muscles of mastication
V Trigeminal
supplies lateral eye muscles/controls lateral rectus muscle
VI abducens
sensations to tongue and soft palate; muscles of the face and stapedius/muscles facial expression
VII Facial
hearing and balance
VIII Vestibulocochlear
sensation to tonsils, pharynx, and soft palate; muscles of pharynx and stylopharyngeus
IX. glossophyaryngeal
sensation to the ear, pharynx, larynx, viscera; muscles of pharynx, larynx, tongue, and smooth muscles of the viscera (voice and swallowing)
X Vagus
muscles of pharynx, larynx, soft palate, and neck/ trapezius & sternocleidomastoid muscles
XI Spinal accessory
strap muscles of neck, extrinsic, and intrinsic muscles of the tongue
XII Hypoglossal
6 cranial nerves that relate to speech hearing and swallowing
trigeminal V Facial VII acoustic or vestibulocochlear nerve VIII glossophayngeal VIIII vagus X Hypoglossal XII
