University of Phoenix Material Brain Structures and Functions Worksheet Below you will see two columns: Brain Structure and Function(s). Items listed under the column‚ “Brain Structure” will list a region of the brain‚ while items under the column titled “Function(s)” will describe the general behavior‚ skill‚ and/or activity of the associated brain structure. Fill in the blank for each of the statements below‚ either listing the brain structure responsible for the function described‚ or providing

(A) I (B) II (C) III (D) IV Item 2 refers to the following diagrams (I and II) representing the iris in bright and dim light respectively. 2. What causes the appearance in I and II to be different? (A) In bright and dim light the circular and radial muscles both contract. (B) In bright and dim light both circular and radial muscles relax. (C)

hemispheres‚ the left hemisphere and the right hemisphere. Each section has its own unique ability to control how feelings and how the body functions. The five sections of the brain are called the frontal lobe‚ parietal lobe‚ occipital lobe‚ the cerebellum and the temporal lobe. The two parts of the brain described in this paper are the frontal lobe and the temporal lobe. These two parts of the brain are very important because they can control how a person communicates and uses information. The frontal

It directs the activity of the heart‚ involuntary smooth muscles‚ and glands while the body is at rest 8). Cerebellum – Small‚ rounded structure that is the most posterior part of the brain. It monitors muscle tone and position and coordinates new muscle movements 9). Hemisphere – One half of the cerebrum. The right hemisphere recognizes patterns and three-dimensional

the human nervous system is the brain. The sensory organs send information to the brain‚ which then sends output to the muscles. The largest part of the brain is the cerebrum. Underneath the cerebrum lies the brainstem‚ and behind that sits the cerebellum. The outmost layer of the cerebrum is called the cerebral cortex‚ which has four lobes. There is a frontal lobe‚ parietal lobe‚ temporal lobe‚ and occipital lobe. The brain develops from three sections known as the forebrain‚ midbrain‚ and hindbrain

The lesions and etiologies of Apraxia of speech and ataxic dysarthria provide a foundation in understanding the correlating similarities and differences composed within the nature and details of these two disorders. Apraxia presents a dysfunction in the integration of coordinated motor plans that facilitate the muscles used in speech production. Motor planning dysfunction is typically caused by lesions within the left hemisphere of the brain‚ at‚ in‚ or‚ around broca’s area‚ which furthermore affects

1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system. 2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron. 3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon. 4.On a neuron‚ the branch-like structures that receive messages from other neurons are the dendrites. 5. The cell body of the neuron‚ responsible

farewell and gave him a final kiss as Emma filled a syringe with a black tincture‚ nightshade. Adrianne held her lover’s hand through the end‚ even though he was numb to it all‚ she felt she had to be there for him as Emma injected the fluid into his cerebellum. After the body was sanitized‚ Adrianne brought Alex to his crude tomb‚ and laid him into his final rest‚ murmuring her truly final farewell and weeping for what could have
