I see you've uploaded multiple images of your worksheet. Let me help you with the blanks step by step. Section C: Neuroglia 1. What are the two types of cells that make up nervous tissue? Neurons and neuroglia 2. What are the functions of neuroglia cells? Support, protect, and maintain homeostasis in neurons; form myelin; and maintain ion balances. 3. List 2 characteristics of neuroglia cells. They can divide and multiply. They are smaller than neurons. Matching Neuroglia Cells with Functions: 4. Satellite cells: Support neurons in the PNS. 5. Oligodendrocytes: Produce myelin in the CNS. 6. Microglia: Phagocytose debris, such as dead brain cells and bacteria. 7. Ependymal cells: Line cavities of the brain and spinal cord and help circulate cerebrospinal fluid. 8. Astrocytes: Anchor neurons and capillaries. 9. Schwann cells: Produce myelin in the PNS. 10. Which glial cells are found only in the PNS? Schwann cells and satellite cells. Section D: Neurons 1. What is the function of neurons? Transmit electrical signals throughout the body. 2. Sam was diagnosed with a brain tumor. Which type of cells would be dividing uncontrollably to form the tumor—neuroglia or neurons? Neuroglia. Matching Parts of a Neuron with Functions: 3. Soma: Contains the nucleus and is the metabolic center of the cell. 4. Dendrites: Slender fibers that conduct impulses toward the soma. 5. Synaptic cleft: Junction of two neurons. 6. Axon terminals: Contain neurotransmitter storage vesicles. 7. Axon: Long fiber that conducts impulses away from the soma. 8. Myelin: Fatty material that protects fibers and speeds impulse transmission. 9. Nodes of Ranvier: Gaps between the myelin sheaths. 10. Axon hillock: Part of the soma that connects to the axon. 12. Label the Neuron: A. Dendrite B. Soma C. Axon hillock D. Axon E. Axon terminal 13. How is an impulse transmitted through a neuron starting at the sensory receptors? Sensory receptors detect stimuli, sending signals through afferent (sensory) neurons to the spinal cord/brain. Motor neurons then transmit responses to effectors (muscles or glands). Section E: Types of Neurons 1. What are the 3 types of neurons? Sensory (afferent), motor (efferent), and interneurons. 2. What is the function of afferent neurons? Carry signals from sensory receptors to the central nervous system. 3. What is the function of interneurons? Facilitate communication between sensory and motor neurons. 4. What is the function of efferent neurons? Transmit signals from the central nervous system to muscles and glands. 5. Which neurons have sensory receptors? Afferent (sensory) neurons. 6. Where are the sensory receptors located on a neuron? On the dendrites of sensory neurons. 7. Which neurons cause movement or action in an organ? Motor (efferent) neurons. 8. Which neuron has ganglia in the PNS? Sensory neurons. Section F: Neuron Physiology 1. Define Irritability and Conductivity: Irritability: The ability of a neuron to respond to stimuli. Conductivity: The ability of a neuron to transmit electrical impulses. 2. Compare the conduction rate in unmyelinated and myelinated fibers: Myelinated fibers conduct impulses faster due to saltatory conduction (impulses jump between nodes of Ranvier). Unmyelinated fibers use continuous conduction, which is slower.
Understand the Problem
The question is an extensive worksheet covering neuroglia and neurons, asking for definitions, functions, and characteristics of these cells, as well as matching them with their functions. This suggests it's part of a biology assignment focused on the nervous system.
Answer
Neurons and neuroglia makeup nervous tissue; neuroglia support, protect, and assist neurons.
Neurons and neuroglia; neuroglia perform supportive roles like forming myelin and maintaining homeostasis.
Answer for screen readers
Neurons and neuroglia; neuroglia perform supportive roles like forming myelin and maintaining homeostasis.
More Information
Nervous tissue is composed of neurons and neuroglia. Neurons are responsible for transmitting signals, while neuroglia support and protect neurons. Neuroglia can also form myelin, a crucial component for fast signal transmission.
Tips
A common mistake is confusing the roles of neurons and neuroglia. Remember that neurons transmit signals, whereas neuroglia provide support and protection.
