Chapter 13 (Part 1) Flashcards
What connects the cerebrum?
Corpus callosum
Main method of communication between 2 hemispheres
Corpus callosum
Hemispheres will receive/send signals to/from the ____ side of the body
opposite
Unique functions not ordinarily performed in the opposing hemisphere
Cerebral lateralization
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
Cerebral cortex
anterior portion of the cerebrum which ends at the central sulcus
Frontal lobe
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
Premotor cortex
Coordinates information from association areas and uses it to perform abstract intellectual function
Prefrontal cortex
Regulates pattern of breathing and vocalization needed for speech
Broca’s area
Controls eye movement needed for binocular vision
Frontal eye field
Posterior to central sulcus
Parietal lobe
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?
Postcentral gyrus
Integrates and interprets sensations to distinguis texture, shapes, degree of sensation
Somatosensory association cortex
Responsible for understanding written or spoken language
Wernicke’s area
Provides comprehensive understanding of current activity, integrates information from association areas regarding vision and hearing
Gnostic area
Posterior portion of the cerebrum
Occipital lobe
What does the occipital lobe contain?
Primary visual cortex, visual association area,
