Worksheet 32

• Cerebellum= responsible for balance, posture, muscle coordination, and muscle tone. (Central nervous system).
• sensory nerves= carry information from the body to the brain, relay information from the brain to the body. (peripheral nervous system).
• Diencephalon= thalamus, hypothalamus, pineal gland. (central nervous system).
• motor nerves= motor neurons, carry impulses from CNS to muscles. (peripheral nervous system).
• Brain stem= controls breathing, heart rate, and blood pressure. (central nervous system)
• Cerebrum= the largest part of the brain, responsible for conscious thought, memory, language, and intelligence. (central nervous system)
• Cranial nerves = nerves that exit the brain and travel to the body. (Peripheral nervous system).
• true or false = a neuron is a cell that can send and receive information. (True)
• True or false = the axon is a long extension from the cell body that receives information. (False)
• true or false = the cerebrum is the smallest part of the brain. (false)
• True or false = the brain, a large, soft mass of nervous tissue, is where information is processed and instructions are issued. (True)
• True or false = the brain stem plays a role in balance. (True)
• This system receives information processes it, and issues instructions. = Central Nervous System
• These nerves carry commands from the brain down the spinal cord and out to the muscles and organs of the body= motor nerves
• These nerves are connected directly to the brain.= cranial nerves.
• This system is the line of communication between the central nervous system and the rest of the body. = Peripheral nervous system.
• These nerves carry information from the internal organs and the outside world to the spinal cord. = sensory nerves.
• The nervous system allows us to experience the world around us. Without our nervous systems, we would not be able to experience the ( taste ) and ( smell ) of a ripe peach, ( hear ) a beautiful piece of music, ( see ) a loved one’s face, or ( feel ) the soft fur of a favorite pet. We would not be able to ( create ), ( move ), or ( think ).
• True or false = transient ischemic attacks (TIAs) are permanent episodes of decreased blood flow (ischemia) to the brain. ( false )
• True or false = A stroke occurs when blood flow to a part of the brain is completely blocked, causing the tissue to die. ( true )
• True or false = Parkinson’s disease is a progressive disease, which means that it gets better with time. ( false )
• True or false = People in the late stages of amyotrophic lateral sclerosis (ALS, Lou Gehrig’s disease) are totally paralyzed, yet their minds remain sharp. ( True )
• True or false = Multiple sclerosis (MS) usually affects the central nervous system first and then moves outward towards the nerves in the hands, feet, and eyes. ( True )
• TRAP = Tremors, rigidity, acinesias, postural instability.
• Risk factors that increase a persons chances of having stroke. = high blood pressure, smoking, Diabetes.
• Most common disabilities resulting from stroke and define them. = Aphasia, Hemiparesis.
• ( Imaging studies ) are often ordered for people with signs and symptoms of a neurological disorder.
• ( Diagnostic tests ), such as computed tomography (CT) scans, allow doctors to see physical abnormalities of the brain, spinal cord, and surrounding bony structures
• ( Electroencephalography ) is used to monitor the electrical activity of the brain.
• A cell that can send and receive information. = Neuron
• The three layers of connective tissue that cover and protect the brain and spinal cord. = Meninges
• the largest part of the brain; involved with voluntary motor control, speech, and processing of sensory input. = Cerebrum
• Coordinates the brain’s commands to the muscles and plays a role in balance. = Cerebellum
• A fatty, white substance that protects the axon and helps to speed the conduction of nerve impulses along the axon. = myelin
• The gap between the axon of one neuron and the den frites of the next. = synapse
• ( sensory receptors ) are cells or groups of cells associated with a sensory nerve.
• The sensory receptors pick up information, called a ( Stimulus ), and translate it into a nerve impulse.
• The sensory receptors that are responsible for ( general sense ) are found throughout the body.
• The sensory receptors that are responsible for ( Special Sense ) are located in the specific sense organs.
• Which special cells detect chemicals in the food we eat, the beverages we drink, and the air we breath?

  ( chemoreceptors )
