AP1 Block 3 - Cerebrum

The cerebral cortex is composed of ONLY _____ mater w/ no fiber tracts.

In 90% of the population the ___ hemisphere is involved with visual-spatial skills, intuition, emotion, and art.

What is the “executive suite” of the nervous system. Communicate, perceive, remember, initiate voluntary movement, etc.

Dispersed within the internal area of the cerebrum of white matter is some deeper grey mater.

Component of limbic system involved with behavior patters (rage, fear, restlessness).

Which sulcus separates the frontal and temporal lobes?

Finding during autopsy in AD patients: clusters of abnormal proteins deposited outside neurons.

Cerebral White Mater Tracts: Conducts nerve impulses between gyri in the same hemisphere.

This left and right asymmetry of the hemispheres is known as HEMISHPERIC ________.

Cerebral White Mater Tracts: nerve impulses from cerebrum to lower parts of CNS (Thalamus, Brain Stem, Spinal Cord).

Each fold of the tissue on the lobes of the cerebrum are called _________. Shallow grooves between them are called _____

The single group of one side of basal ganglia are called the ________.

Damage to basal ganglia has also been found in OCD and ADHD patients.

Wernicke’s fluent aphasia is known as “word-salad”

Area that interprets the meaning of speech by recognizing spoken words.

The main 4 components that “we” need to focus on of the limbic system are?

Portion of the hippocampus that converts new information to long-term memory.

Other than the Corpus Callosum, other Commissural Tracts include the anterior and posterior commissures

The Basal Ganglia help regulate initiation and termination of ________.

Area that is involved with planning and production of speech.

Which sulcus separates the frontal and parietal lobes?

The _____ cerebral hemisphere of most people, regardless of L/R handedness contains the language area. Broca/Wernicke

The gyri and fissures form during embryo development when gray mater enlarges slower than white matter.

Inability to carry out purposeful movements in the absence of paralysis

The loss of ability to form new memories resulting from hippocampus damage is known as?

Each independent hemisphere communicates through the largest fiber bundle in the brain known as the hard body:

Disabling senile dementia. Loss of reasoning and ability to care for oneself that affects geriatric population.

The Lentiform nucleus consists of the _____ and _____.

Cerebral White Mater Tracts: nerve impulses from gyri in one hemisphere to another. Corpus Callosum

What is an early sign of Alzheimer Disease?

The most prominent fissure is the __________.

A band of nerve fibers extending from the hippocampus to the mammillary body of the hypothalamus forming an arch.

Damage to basal ganglia cause uncontrolled shaking and can be seen in which degenerative disease process?

The cerebral cortex is the outer rim of _____ mater containing billions of neurons.

The Basal Ganglia is comprised of ___ nuclei deep within each cerebral hemispheres.

The Cingulate Gyrus is involved with ____ formation. Also processing, leaning, and memory. Sensory input to memory.

The emotional brain is known as the ______ system. Rage, pain, pleasure, etc. Encircle the upper part of brain stem.

Deeper grooves between gyri are termed ________.

People know what they want to say, but can not speak.

Inability to use or comprehend words

The caudate nucleus of the basal ganglia and the thalamus are separated from the lentiform nucleus by the ________.

Area that communicates with motor cortex and other similar areas to analyze, recognize and act on sensory input.

Each hemisphere of the cerebral cortex is concerned with sensory and motor functions for that side of the body.

Inability to recognize the significance of sensory stimuli (sound, sight, smell, taste, touch)
