Flashcards in Chapter 13 (Part 1) Deck (40):
What connects the cerebrum?
Main method of communication between 2 hemispheres
Hemispheres will receive/send signals to/from the ____ side of the body
Unique functions not ordinarily performed in the opposing hemisphere
What are the actions of the right hemisphere?
Analyze sensory information, relate body to sensory environment, imagination, artistic skill
What are the actions of the left hemisphere?
Genearl interpretation, analytical thought, production of speech
Superficial layer of gray matter
anterior portion of the cerebrum which ends at the central sulcus
What does the frontal lobe contain?
Primary motor cortex and premotor cortex
Issues voluntary commands to skeletal muscle
Primary motor cortex
Plans and coordinates learned movement
Coordinates information from association areas and uses it to perform abstract intellectual function
Regulates pattern of breathing and vocalization needed for speech
Controls eye movement needed for binocular vision
Frontal eye field
Posterior to central sulcus
What does the parietal lobe contain?
Primary somatosensory cortex, gnostic, wernicke's, somatosensory association
Receives general sensory information
Primary somatosensory cortex
What are some examples of general senses?
Pain, temperature, touch, pressure, vibration, proprioception
Where is the primary somatosensory cortex located?
Integrates and interprets sensations to distinguis texture, shapes, degree of sensation
Somatosensory association cortex
Responsible for understanding written or spoken language
Provides comprehensive understanding of current activity, integrates information from association areas regarding vision and hearing
Posterior portion of the cerebrum
What does the occipital lobe contain?
Primary visual cortex, visual association area,
Receives visual information from the eyes
Primary visual cortex
Monitors patterns in primary visual cortex and interprets results
Visual association area
What does the temporal lobe contain?
Primary auditory cortex, auditory association area, primary olfactory cortex
Receives auditory information from the ear
Primary auditory cortex
Interprets auditory stimulation and stores memory from it
Auditory association area
Receives information about smell from the nose
Primary olfactory cortex
Deep to frontal, parietal and temporal lobes
Receives and processes taste information from the tongue
Primary gusatory cortex
Location of myelinated axons
Central white matter
Bundle of axons in the CNS
Connect different regions of the cerebral cortex within the same hemisphere
Extend between cerebral hemispheres
Link cerebral cortex to inferior brain regions and spinal cord
Collection of cell bodies (gray matter)
What are the functions of the cerebral nuclei?
-Subconscious control of skeletal muscle tone
-Regulate motor output from cerebral cortex
-Inhibit unwanted movement
