Two Main Cells Nervous System Health And Social Care The two main types of cells in the nervous system are neurons and neuroglia. Neurons are also called functional units. They are the actual nerve cells that transmit impulses of the nervous system. Each neuron consists of three basic parts: a cell body, axon, and one or more dendrites. The cell body, also called the soma, contains the nucleus, cytoplasm, and other organelles.
Week 5 Forum Student’s Name Institutional Affiliation Date The amygdala and hippocampus are the main parts of the brain whose responsibility is the regulation of memory. The amygdala is divided into two, the right and left hemispheres. The right hemisphere is responsible for negative emotions like fear and sadness while the left hemisphere induces both the pleasant and unpleasant emotions when stimulated. These hemispheres have independent memory systems but they work together to encode, store and interpret information. The hippocampus on the other side is responsible for the production of corticosteroids (chemicals that produce physiological responses to stimuli).
Provide a description of where the damage may occur and of the eye. the visual is found inside the thalamus of the mind. The average geniculate core which what functional visual deficits may arise. manages sound-related data is additionally in the thalamus. "Amblyopia, ordinarily regarded as languid eye, is the eye condition noted by decreased vision not correctable by glasses or contact lenses and is not because of any eye sickness.
Unit 7 Assignment 2: The Effects of Selected Drugs and Diseases on the Central Nervous System 1. The CNS otherwise known as the Central Nervous System is comprised of the brain which is continuous with the spinal cord. Since the CNS is made up of the brain and spinal cord it is protected by the hard bony skull and vertebral column. (Pages 418- 420) 2. The BBB also known as the Blood Brain Barrier which in conjunction with the Cerebrospinal Fluid or CSF is what nourishes and protects the cells of the CNS.
Medulla Located at the top of the spinal cord. Controls breathing, heart rate, and blood pressure. 10. Pons Above the medulla, and controls sensory information. It also controls facial exspretions.
Nerve coverings—fibrous connective tissue * Endoneurium—surrounds individual fibers within a nerve * Perineurium—surrounds a group (fascicle) of nerve fibers * Epineurium—surrounds the entire nervea 4) Define the following parts of the brain & spinal cord. Your definition should include where the specific part is found, structure, function and any other information you feel is pertinent. 1) Brainstem- Consists of three parts of brain; named in ascending order: the medulla oblongata, pons, and midbrain- Structure—white matter with bits of gray matter scattered through it-Function—gray matter in the brainstem functions as reflex centers Heartbeat, respirations, and blood vessel diameter -Sensory tracts in the brainstem conduct impulses to the higher parts of the brain- Motor tracts conduct from the higher parts of the brain to the spinal cord 2) Diencephalon- Hypothalamus, a) Posterior pituitary gland, pituitary stalk, & gray matter b) Major center for controlling the ANS c) Functions of most internal
___ cells of the retina are inhibited by glutamate in the dark, but excited in the light when glutamate secretion stops. (a) Ganglion; (b) Rod; (c) Bipolar; (d) Amacrine; (e) Cone 13. In the ___, there are no rod cells, but small closely spaced cone cells with “private lines” to the brain. (a) fovea centralis; (b) optic disc; (c) ora serrata; (d) ciliary body; (e) fundus 14. As you focus on a nearby object while it moves closer to your face, all of the following processes occur except: (a) the pupil constricts; (b) the medial rectus muscles contract; (c) the lenses become thicker; (d) the ciliary muscle relaxes; (e) the eye shifts from the scotopic to photopic mode.
Cholinergic transmission can be defined as the physiological process that operates the neurotransmitter acetylcholine (ACh) to communicate between cells (Wess, 1993). ACh is used in all movement of the muscles, and the neurotransmission of ACh occurs in the peripheral (PNS) and central nervous systems (CNS). ACh has broadly shown a

Four Ventricles of the brain are connected cavities within the brain, where cerebrospinal fluid is produced. Hypothalamus is a region of the brain in partnership with the pituitary gland that controls the hormonal processes of the body as well as temperature, mood, hunger, and thirst. Optic Chiasm is located beneath the hypothalamus and is where the optic nerve crosses over to the opposite side of the brain. Pineal Gland controls the response to light and dark. The exact role of the pineal gland is not certain.
