Term
Executive Functions
Definition
involves the highest level of human cognitive ability. It is possible to have a language impairment and still have intact executive functions.

What abilities are included in visual perception?
Definition
discriminate, analyze,recognize, interpret visual stimuli, visually construct using eye-hand coordination
Term
Why is it important to test a patient's visual fields?
Definition
the patient’s visual fields must be assessed to rule-out hemianopsia and visual inattention
Term
Language
Definition
Language is a system of symbols used to functionally communicate. It involves the use of spoken, written, manual, or other symbol systems to convey one’s thoughts for expression or reception of information.
Term
What are common communication modes
Definition
Listening, speaking, reading, and writing are common communication modes. Sign language, gestures, drawings, and picture symbols may also be used to communicate
Term
Types of Neurons
Definition
Sensory, Motor, Interneurons
Term
Sensory Neurons
Definition
sensors and are sensitive to light, sound, touch, temperature, smell, and chemical input
Term
Motor neurons
Definition
are actors and receive excitation from other cells giving rise to muscle impulses and secretion of hormones.
Term
Interneurons
Definition
connect one neuron to another and can notify motor neurons to move a part of the body that has detected dangerous sensory information
Term
How many neurons in the human brain?
Definition
More than 100 billion
Term
Parts of a neuron
Definition
body (soma), filamental extensions (dendrites), and longer fibers (axons).

What is the function of dendrites?
Definition
receive stimuli from other neurons
Term
What is the function of axons?
Definition
send stimuli to other neurons, glands, and muscles.
Term
How are messages transmitted between neurons?
Definition
Transmission is electrochemical via neurotransmitters; One neuron stimulates another and so on
Term
What makes up the CNS?
Definition
The brain and Spinal cord
Term
What does the spinal cord contain?
Definition
Each segment of the spinal cord has sensory and motor nerves that innervate the skin, organs, and muscles of the body
Term
What doesA substantial loss of neurons in the adult brain often leads to?
Definition
Disability

1,200 to 1,400 grams (2.6 – 3.1 lbs.)
Term
What are the three layers of tissue that protect the brain?
Definition
Meninges- Dura, Arachnoid, Pia
Term
Subarachnoid space
Definition
•is between the arachnoid membrane and pia mater and contains blood vessels and cerebrospinal fluid
Term
Cerebrospinal Fluid (CSF)
Definition
clear and colorless fluid that circulates throughout the brain and spinal cord, cushioning and protecting them from injury,flows from one ventricle to the next and then into the subarachnoid space
Term
Ventricles
Definition
fluid-filled cavities in the brain;two lateral ventricles, the third ventricle, and the fourth ventricle;Ventricles and the central canal of spinal cord contain CSF.
Term
choroid plexus
Definition
Located in each ventricle; produces CSF-is fluid like blood plasma formed by cells in the four ventricles
Term
Connection of Ventricles
Definition
Two lateral ventricles are located in the interior hemispheres of forebrain. They connect with the third ventricle at a posterior point which connects to the fourth ventricle in the medulla;drain through the foramin of luska and mejendi
Term
Hydrocephalus
Definition
occurs when the flow of CSF is obstructed and accumulates in the ventricles or subarachnoid space thereby increasing pressure on the brain. In children this condition causes the bones in the head to spread and their head can become very large.
Term
cerebral corxtex
Definition
also known as the cerebrum;the largest part of the brain and is involved in complex thinking, learning, personality, movement, touch, and vision
Term
cerebral cortex 2
Definition
is composed of gray matter or cell bodies totaling more than 6 billion along with their dendritic connections; left and right hemishpere;The cerebral cortex is actually the cover of the cerebri; the cortex is the cover and is grey
Term
Gray Matter
Definition
•Gray matter contains nerve cell bodies, glial cells, capillaries, axons, and dendrites. Gray matter directs sensory or motor stimuli to the interneurons of the CNS for responsiveness via synaptic activation
Term
corpus callosum
Definition
a longitudinal fissure comprised of two large bundles of axons thst connects the right and left hemispheres;comprised of cortical association fibers and subcortical connections;functioning is critical to transmission of information between the left and right hemispheres
Term
contralateral innervation
Definition
The two hemispheres receive sensory information form the contralateral side of the body and effect movement on the opposite side of the body

typically best at processing speech and language and is involved in verbal memory
Term
right hemisphere
Definition
–typically best at processing paralinguistic information and pragmatics as well as non-linguistic information that is visual, spatial, musical, and emotional.
Term
5 lobes of the brain
Definition
Frontal, Temporal, Occipital, Parietal, Insular
Term
Frontal Lobe
Definition
The frontal lobes let us know what we are consciously doing; Emotional responses, memory for habits, motor activities, and expressive language are mediated by the frontal lobes; affected by alcohol
Term
precentral gyrus
Definition
- specialized for control of movement
Term
prefrontal area of the cortex
Definition
involved in planning and initiating, concentration, emotional responses, and disinhibition of behaviors. It also play a role in one’s ability to switch sets and adapt to changes.
Term
perservation

Term
We can assume that a person with aphasia still has all of their cognitive functions in tact.
True or False?
Definition
False,
A person who has aphasia has a primary disorder in the area of language, and we cannot assume their cognitive functions are intact
Term
Cognitive impairment and language impairment are intities that have no influence one another.
True or False?
Definition
False,
Cognitive impairment and language impairment are unique entities that influence one another. For example, memory impacts language and lots of people have problems with both cognitive and language issues
