Understanding Nerve Tissues

This video from Mumu Math and Science explains nerve tissues, which are found in the brain, spinal cord, and peripheral systems. It describes how nerve cells, or neurons, transmit electrical signals throughout the body, enabling communication between the brain and body. The video details the structure of neurons, including the cell body, dendrites, and axon, and explains how signals pass through these parts. The video concludes with a call to action to subscribe for more educational content.

Where are nerve tissues primarily located in the body?

• In the brain, spinal cord, and peripheral systems

• In the digestive system

• In the heart and lungs

• In the skin and muscles

What is the main function of neurons?

• To support blood circulation

• To transmit electrical signals

• To store energy

• To produce hormones

What does the cell body of a neuron contain?

• Only mitochondria

• Only ribosomes

• The nucleus and other organelles

• Only the nucleus

How do dendrites appear visually?

• Like flat sheets

• Like small spheres

• Like tree branches

• Like smooth tubes

What is the role of dendrites in a neuron?

• To produce electrical signals

• To store nutrients

• To receive electrical signals from other neurons

• To transmit signals to muscles

What is the function of the myelin sheath?

• To store energy

• To produce electrical signals

• To insulate the axon

• To connect neurons

What happens at the axon terminal?

• Signals are communicated to other cells

• Signals are stored

• Signals are destroyed

• Signals are generated
