Exploring The Structure And Function Of Nervous Tissue

The video tutorial provides an in-depth look at the nervous system, focusing on the structure and function of neurons. It explains the components of neurons, including the cyton and axon, and details the process of nerve impulse transmission. The tutorial also covers different types of neurons based on structure and function, the role of the myelin sheath, and the structure of nerves. Key concepts such as neurotransmitters, synapses, and the node of Ranvier are discussed, providing a comprehensive understanding of how the nervous system facilitates communication within the body.

What are the two main components of the nervous system?

• Neurons and muscles

• Neurons and nervous tissues

• Nervous tissues and blood vessels

• Neurons and bones

What is another name for the cell body of a neuron?

• Myelin

• Cyton

• Dendrite

• Axon

What surrounds the myelin layer of an axon?

• Axoplasm

• Neurolemma

• Dendrites

• Nissl granules

What is the role of neurotransmitters in the nervous system?

• They transmit impulses across synapses

• They insulate the axon

• They create Schwann cells

What is the gap between the axon terminal of one neuron and the dendrite of another called?

• Node of Ranvier

• Neurolemma

• Synapse

• Axolemma

What is the function of sensory neurons?

• To connect sensory axons

• To send signals from sense organs to the CNS

• To transmit signals from the CNS to muscles
