Lesson 2 Vocab

What is the Peripheral Nervous System?

• The part of the nervous system that includes the brain and spinal cord.

• The part of the nervous system that includes nerves and is not part of the brain and spinal cord.

• The system that controls only the sensory functions of the body.

• The network of nerves that connects the brain to the rest of the body.

What does the Central Nervous System include?

• The heart and the lungs

• The brain and the spinal cord

• The stomach and the intestines

• The liver and the kidneys

What is the definition of nerves as provided in the learning material?

• Cells that transmit electrical signals

• A single neuron

• A bundle of neurons

• The part of the brain that controls movement

What is the role of sensory neurons?

• To produce hormones

• To receive external stimuli and pass signals to the central nervous system

• To contract and relax muscles

• To transport nutrients and oxygen in the blood

What is the function of motor neurons?

• To carry sensory information to the brain

• To pass signals from the brain or spinal cord to a muscle or gland

• To support and nourish neurons

• To form the blood-brain barrier

Which part of the motor neuron is responsible for receiving signals?

• Axon terminal

• Muscle

• Dendrites

• Axon

What is the function of a neuron?

• To provide structural support to the brain

• To send signals or transmit nerve impulses

• To pump blood through the body

• To filter waste from the blood

Which part of the neuron is responsible for receiving incoming signals from other neurons?

• Axon Terminal

• Myelin Sheath

• Dendrite

• Node of Ranvier

What is the role of the myelin sheath in a neuron?

• It generates electrical impulses.

• It receives signals from other neurons.

• It speeds up the transmission of nerve impulses.

• It connects the neuron to the bloodstream.

What is the function of dendrites in a neuron?

• To send signals to other neurons

• To receive signals from other neurons

• To protect the neuron

• To provide energy to the neuron
