Neuron that conducts impulses away from the CNS to muscles and glands _____ 9. Sensory receptors found in muscle and tendons, which detect their degree of stretch _____ 10. Changes, occurring within or outside the body, that affect nervous system functioning. _____ 11. Neuron that conducts impulses toward the CNS from the body periphery _____ 12. Chemicals released y neurons that stimulate other neurons, muscles or glands. Supporting Cells List the Glia cells that are found in the brain. Glial cells present in large numbers in area of bacterial infection in the brain would most likely be _____________________________. Which Glial cells can transmit an impulse. ___________________________ Why are most brain tumors composed of Glial cells? What importance is the Schwann cell? The oligodendrite cell? Where are each found? Organization: Choose the key responses that best correspond to the descriptions provided in the following statements. Insert the appropriate term in the answer blank. Autonomic nervous system Central nervous system Peripheral nervous system Somatic nervous system 1. ____________________________ Nervous system subdivision that is composed of the brain and spinal cord. 2. ____________________________ Subdivision of the PNS tat controls voluntary activities such as the activation of skeletal muscles. 3. ____________________________ Nervous system subdivision that is composed of the cranial and spinal nerves and ganglia. 4. ____________________________ Subdivision of the PNS that regulates the activity of the hear and smooth muscle, and of glands; it is also called the involuntary nervous system. Structure and Function of the Nervous System Structures: 1) 2) 3) 4) 5) 6) Functions: 1) 2) 3) - - detect stimuli neurons are also called _________________________ - integrates sensory information by analyzing and storing, making decisions neurons are also called __________________________ and are most of the neurons in the body - respond to stimuli neurons are also called ___________________________ which carry information out of the brain and spinal cord
