Directions: ANSWER USING COMPLETE SENTENCES! Use the information you have been given to answer questions about:The Nervous System: The Neuron (Nerve Cell)

*To improve your MATH SKILLS spend at least 20 minutes practicing them using IXL.COM. (REMEMBER TO ENTER YOUR USER NAME AND PASSWORD WHEN LOGGING ON! THAT WILL BE PROOF THAT YOU DID IT!)

Level#1

A neuron is a nerve cell. Neurons come in many sizes and shapes. In fact, one neuron in your leg can be more than 3 feet long! Neurons are the basic units of structure that make up the nervous system. A typical neuron has three main parts. The largest part of the neuron is the cell body. There are long fibers that branch from the cell body. Some of these fibers carry messages from other neurons into the cell body. These fibers are called dendrites. Other fibers carry messages away from the cell body to other neurons. These fibers are called axons.

1. Where do the messages that some fibers carry from other neurons go into?




2. What are the fibers that carry messages into the cell body called?




3. What are the fibers that carry messages away from the cell body to other neurons called?







Level#2

A neuron is a nerve cell. Neurons come in many sizes and shapes. In fact, one neuron in your leg can be more than 3 feet long! Neurons are the basic units of structure that make up the nervous system. A typical neuron has three main parts. The largest part of the neuron is the cell body. There are long fibers that branch from the cell body. Some of these fibers carry messages from other neurons into the cell body. These fibers are called dendrites. Other fibers carry messages away from the cell body to other neurons. These fibers are called axons. Sensory neurons are connected to your sense organs. The eyes, ears, nose, tongue, skin are your sense organs. Sensory neurons take messages away from the sense organs to the brain and spinal cord.

1. What do long fibers that branch from the cell body do, and what are these fibers called?





2. Where do other fibers that carry messages away from the cell body send their messages to, and what are these fibers called?





3. What are sensory neurons connected to, and what do sensory neurons do?







Level#3

Neurons are the basic units of structure that make up the nervous system. A typical neuron has three main parts. The largest part of the neuron is the cell body.

Other fibers carry messages away from the cell body to other neurons. These fibers are called axons. Sensory neurons are connected to your sense organs. The eyes, ears, nose, tongue, skin are your sense organs. Sensory neurons take messages away from the sense organs to the brain and spinal cord. Motor neurons carry messages away from the central nervous system to muscles and glands. Glands are organs that make chemical substances that are used or released by the body. Muscles and glands respond to information from the brain. 

1. Explain where other fibers that carry messages away from the cell body deliver their messages to, and what these fibers are called.








2. Explain what sensory neurons are connected to, and what sensory neurons do.








3. Explain what motor neurons do, what glands do, and what muscles and glands respond to.
