Structures
What is Right and Left Hemisphere
What is the function of the Occipital lobe?
Visual processing and/or projecting info to other parts of the brain for further processing
What lobe is the Primary Auditory cortex located in?
Temporal lobe
What is gray matter and what does it do?
These are the cell bodies, and this is where neural information is received. (Cortex and nuclei)
How many Cranial Nerves are there
12!
What are the Cerebrum's four major lobes? and demonstrate their general location on your head!
What is Frontal, Parietal, Temporal, and Occipital
What is the function of the parietal lobe's posterior parietal cortex?
Superior: Interpret visual and spatial info
Inferior: word meaning, link actions with a word
Angular: semantics, reading
What nervous system are spinal nerves a part of? Describe input and output through the spinal nerves
The CNS. They may recieve afferent (sensory) imput from the PNS and deliver efferent (motor) output to the PNS.
What is white matter and what makes it carry signals fast?
Myelin makes it fast and it is made up of axons.
What Nerve is associated with Hearing and Balance
CN 8 the vestibulocochlear nerve!
What are the different sections of the spinal cord from top to bottom?
What is Cervical, Thoracic, Lumbar, and Sacral.
THE FRONTAL LOBE plans and executes movement and is an integrative center for cognition. What may happen if the Primary Motor Cortex (M1) is damaged?
What does the Basal ganglia do and where is it?
What is a group of subcortical nuclei in the cerebrum and midbrain area; chooses best action to complete a goal or task.
What is a type of agnosia
auditory, visual, prosopagnosia (faces), pure word deafness, alexia w/o agraphia
What innervates the tongue's extrinsic and intrinsic muscles?
CN 12 the Hypoglossal nerve!
What are the components of the brain stem? List them from top to bottom from a sagittal slice view.
What is Midbrain, Pons, Medulla!
What are the two parts of the diencephalon and some of their functions?
The Thalamus - info super highway, sensory info, motor info, emotion/memory/autonomic control
The hypothalamus- homeostasis, hunger, temp regulation, metabolic energy
THE LIST IS ENDLESS
Where is the Postcentral gyrus and what does it do?
This it located in the parietal lobe past the central sulcus. It is part of the primary somatosensory cortex which has somatotopic organization for processing sensory input.
What does the precentral gyrus consist of and what does it receive information from ?
This consists of the primary motor cortex! Which is mapped area that receives input from the cerebellum, basal ganglia, premotor area, and primary somatosensory cortex
What is the CN V
The trigeminal nerve! it is important for somatosensation and speech! It is both efferent and afferent
Where is Brocas area and Wernickes area located? lobe and hemisphere?
What is Left Hemisphere, Broca in frontal, Wernicke in Temporal
What are the functions of the Premotor Area (PMA) and the Supplementary Motor area (SMA)? How could this affect speech?
The PMA plans actions and sends info to the Primary Motor cortex. The SMA involves sequential actions, complex planning and the cognitive aspects of motor actions. Speech could be affected by someone being unable to coordinate their articulators etc etc
What does the temporal lobe do?
sound processing, semantic knowledge, recognize complex objects (ex: faces), language comprehension
What are the three types of info processing in the cerebral cortex?
Serial/Hierarchal
Parallel
Dorsal and Ventral
Salivation, mucous production, innervate lover motor neurons
transmits taste sensation from the
tongue and transmits tactile sensation from
skin areas behind the ear and within the
external auditory canal.
