Which neuron sends impulses to a muscle?
- A.
Interneuron
- B.
Sensory neuron
- C.
Motor neuron
- D.
Nerve impulse
Correct Answer
C. Motor neuronExplanation
A motor neuron is responsible for sending impulses from the central nervous system to a muscle, causing it to contract or move. Unlike sensory neurons, which transmit information from sensory organs to the central nervous system, motor neurons specifically control muscle movement. Interneurons, on the other hand, facilitate communication between sensory and motor neurons within the central nervous system. Therefore, the correct answer is motor neuron.Rate this question:

A sensory neuron carries nerve impulses from one neuron to another.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
A sensory neuron does not carry nerve impulses from one neuron to another. Instead, sensory neurons are responsible for transmitting nerve impulses from sensory receptors (such as those in the skin or eyes) to the central nervous system (brain and spinal cord). Once the impulses reach the central nervous system, they are then transmitted to other neurons for further processing and response. Therefore, the statement that a sensory neuron carries nerve impulses from one neuron to another is incorrect.Rate this question:

When a neuron carries a message, it is called what?
- A.
Axon
- B.
Dendrites
- C.
Nerve impulse
- D.
Neuron
Correct Answer
C. Nerve impulseExplanation
When a neuron carries a message, it is referred to as a "nerve impulse." This term describes the electrical signal that travels along the axon of a neuron, allowing for communication between different parts of the nervous system. Axon and dendrites are structural components of a neuron, while a neuron is the overall name for the specialized cells that transmit information in the nervous system. However, "nerve impulse" specifically denotes the action potential or electrical signal that is propagated along the axon of a neuron.Rate this question:
-
- 5.
An axon carries the impulses toward the cell body.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
An axon carries the impulses away from the cell body, not towards it. The cell body receives the impulses from other neurons and sends them along the axon to other neurons or target cells. Therefore, the statement in the question is incorrect, and the correct answer is False.Rate this question:

Dendrites carry a message toward a neuron cell body.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Dendrites are the branch-like structures of a neuron that receive signals from other neurons and carry them towards the cell body. These signals, or messages, can be in the form of electrical impulses or chemical signals. Once the messages are received by the dendrites, they are then transmitted to the cell body where further processing and integration of information takes place. Therefore, it is correct to say that dendrites carry a message toward a neuron cell body.Rate this question:

The centeral nervous sysytem has a ____ and a spinal cord
Correct Answer
BrainExplanation
The central nervous system consists of the brain and the spinal cord. The brain is the control center of the body, responsible for processing information, coordinating movements, and regulating bodily functions. It receives and interprets signals from the sensory organs and sends out instructions to the muscles and organs through the spinal cord. The spinal cord, on the other hand, acts as a pathway for transmitting sensory and motor signals between the brain and the rest of the body. Together, the brain and spinal cord play a crucial role in the functioning of the nervous system.Rate this question:

What system lets air move into the lung (part of the system is outside the lungs & part is inside the lungs)?
- A.
Bronchi
- B.
Trachea
- C.
Pharynx
- D.
Alveoli
Correct Answer
A. BronchiExplanation
The bronchi are the part of the respiratory system that allows air to move into the lungs. They are a pair of large air tubes that branch off from the trachea and lead into each lung. The bronchi are responsible for carrying air from the outside of the lungs into the smaller airways called bronchioles, which then lead to the alveoli where gas exchange takes place. Therefore, the bronchi are the correct answer as they are the specific part of the respiratory system that allows air movement into the lungs.Rate this question:

The diaphram is a small muscle that doesn't play an important role in breathing.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The given statement is false. The diaphragm is a crucial muscle involved in the process of breathing. It separates the chest cavity from the abdominal cavity and contracts and relaxes to facilitate inhalation and exhalation. When the diaphragm contracts, it moves downward, creating more space in the chest cavity and allowing the lungs to expand and fill with air. When it relaxes, it moves upward, decreasing the space in the chest cavity and causing the lungs to deflate and release air. Therefore, the diaphragm plays a vital role in the breathing process.Rate this question:
