Nervous Tissue
Nervous Tissue: Overview
This topic covers concepts such as Dendrites, Axon of a Neuron, Myelinated Nerve Fiber, Non-myelinated Nerve Fiber, Nervous Tissue, Neurons, Types of Neurons, and Cyton.
Important Questions on Nervous Tissue
Apolar neurons are found in _____.
What is cyton projection?
Define cyton and its function.
The non-myelinated nerve fibres surround:
The non-myelinated nerve fibres are the nerve cell in the autonomous nervous system.
The non-myelinated nerve fibres is a neuron that does not have _____ (myelin/nerve) sheath surrounded the axon.
Explain Non-myelinated nerve fibre.
Schwann cells in the peripheral nervous system produce myelin sheath?
Nervous tissues are derived from
The functional unit of nervous system is
Which of the following statements is incorrect
Neuroplasm of neuron contains myelin sheath, neurofibrils and Schwann cells.
Cyton of neuron contains smaller branches called dendrites; these conduct impulses away from the Cyton.
Myelin sheath is not continuous. It is interrupted by gaps called nodes of Ranvier.
A long branch that arises from cyton is called axons which carry impulses towards the cyton.
Match the following:
| Column A | Column B |
| 1. Dendron | a. Controlled by the medulla oblongata |
| 2. Vertebral column | b. Carry impulses to effector organs |
| 3. Impulses | c. Irregular folds on outer surface |
| 4. Effector organs | d. Nerve |
| 5. Bundles of axons | e. Fatty white substance covering an axon |
| 6. Swallowing | f. Distributes nutrients to the brain |
| 7. Motor nerves | g. Glands and muscles |
| 8. Myelin sheath | h. Has many branches |
| 9. Cerebrum | i.Messages encoded as electrical signals |
| 10. Cerebrospinal fluid | j. Protects the spinal cord. |
Identify and name the type of tissue present in the Nerve cord.
Inter-neuronal space contains
The membrane covering the neuron is:
The body of the neuron is:
The thin cytoplasmic processes of neurons are
The cytoplasmic processes that carry impulses away from the cyton are
