What are the two major parts of the Peripheral Nervous System?
-
Central Nervous System and Peripheral Nervous System
-
Somatic Nervous System and Autonomic Nervous System
-
Somatic Nervous System and Central Nervous System
Correct Answer
A. Somatic Nervous System and Autonomic Nervous SystemExplanation
The correct answer is Somatic Nervous System and Autonomic Nervous System. The peripheral nervous system consists of two major parts: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements and transmits sensory information to the central nervous system. The autonomic nervous system regulates involuntary bodily functions, such as heart rate, digestion, and breathing. Therefore, these two parts together make up the peripheral nervous system.Rate this question:

Nerve cells are called __________.
-
Impulses
-
Neurons
-
Enzymes
Correct Answer
A. NeuronsExplanation
Nerve cells are called neurons. Neurons are specialized cells that transmit information through electrical and chemical signals in the nervous system. They play a crucial role in the communication and coordination of different parts of the body, allowing us to perceive and respond to stimuli. Neurons have a unique structure with dendrites that receive signals, an axon that transmits signals, and synapses that allow communication with other neurons or target cells. Therefore, the correct answer is neurons.Rate this question:

Nerve cells send messages in the form of electrical signals called __________.
-
Impulses
-
Neurons
-
Enzymes
Correct Answer
A. ImpulsesExplanation
Nerve cells, also known as neurons, communicate with each other by sending electrical signals called impulses. These impulses travel along the length of the neuron, allowing for the transmission of information throughout the nervous system. Neurons are specialized cells that are capable of generating and transmitting these impulses, which play a crucial role in the functioning of the nervous system and the communication between different parts of the body. Enzymes, on the other hand, are not directly involved in the transmission of electrical signals in nerve cells.Rate this question:

What are the three parts of a neuron?
-
Nucleus, Axons and Pons
-
Nucleus, Dendrites and Pons
-
Nucleus, Dendrites and Axons
Correct Answer
A. Nucleus, Dendrites and AxonsExplanation
The three parts of a neuron are the nucleus, dendrites, and axons. The nucleus is the central part of the cell that contains genetic material. Dendrites are the branch-like extensions that receive signals from other neurons and transmit them to the cell body. Axons are long, slender extensions that transmit signals away from the cell body to other neurons or target cells.Rate this question:

What are the neurons that take the messages from the senses to the brain?
-
Motor Neurons
-
Sensory Neurons
-
Medulla Oblongata
Correct Answer
A. Sensory NeuronsExplanation
Sensory neurons are responsible for transmitting messages from the senses to the brain. These specialized neurons are located in the sensory organs such as the eyes, ears, nose, tongue, and skin. They detect various stimuli such as light, sound, smell, taste, and touch, and convert them into electrical signals that can be understood by the brain. The sensory neurons then transmit these signals to the brain, allowing us to perceive and interpret the information from our environment.Rate this question:

What are the neurons that carry instructions from the brain to the body and what action to take?
-
Motor Neurons
-
Sensory Neurons
-
Medulla Oblongata
Correct Answer
A. Motor NeuronsExplanation
Motor neurons are the neurons that carry instructions from the brain to the body and determine what action to take. They transmit signals from the central nervous system to the muscles, allowing for voluntary movements and controlling bodily functions. Motor neurons play a crucial role in coordinating movement, allowing us to perform tasks such as walking, talking, and grasping objects.Rate this question:

It is a thick bunch of nerves that start at the brain stem and go down the back. It is protected by the spinal column.
-
Spinal Cord
-
Pons
-
Pituitary Gland
Correct Answer
A. Spinal CordExplanation
The given description states that it is a thick bunch of nerves that start at the brain stem and go down the back, and it is protected by the spinal column. This perfectly matches the characteristics of the spinal cord, which is a long, cylindrical structure made up of nerve fibers that transmit signals between the brain and the rest of the body. The spinal cord is indeed protected by the spinal column, making it the correct answer.Rate this question:

What is a group of cells that produces and secretes or gives off chemicals?
-
Gland
-
Hormones
-
Organs
Correct Answer
A. GlandExplanation
A gland is a group of cells that produces and secretes or gives off chemicals. Glands are responsible for producing various substances such as hormones, enzymes, and sweat. They play a crucial role in regulating bodily functions and maintaining homeostasis. Glands can be classified as exocrine or endocrine, depending on whether they release their secretions into ducts or directly into the bloodstream. This explanation aligns with the answer choice "Gland."Rate this question:

What are chemical messengers that transfer information and instructions from one set of cells to another?
-
Organs
-
Hormones
-
Glands
Correct Answer
A. HormonesExplanation
Hormones are chemical messengers that transfer information and instructions from one set of cells to another. They are produced by various glands in the body and are released into the bloodstream, where they travel to target cells or organs to regulate various bodily functions. Hormones play a crucial role in maintaining homeostasis, growth, development, and reproduction.Rate this question:

It is in charge of body processes that happen slowly, such as cell growth.
-
Nervous System
-
Endocrine System
-
Digestive System
Correct Answer
A. Endocrine SystemExplanation
The endocrine system is responsible for regulating and controlling various body processes that occur slowly, such as cell growth. It does this by producing and releasing hormones into the bloodstream, which then travel to target cells or organs to initiate specific actions. Unlike the nervous system, which primarily controls rapid responses, the endocrine system works more gradually and helps maintain homeostasis in the body. The digestive system is not involved in regulating cell growth or other slow body processes.Rate this question:

Which is the cell body of a neuron?
-
Nucleus
-
Dendrites
-
Axons
Correct Answer
A. NucleusExplanation
The cell body of a neuron, also known as the soma, contains the nucleus. The nucleus is responsible for controlling the functions of the cell and contains the genetic material of the neuron. It plays a crucial role in maintaining the overall health and functioning of the neuron by regulating the synthesis of proteins and other important molecules. The dendrites and axons, on the other hand, are extensions of the cell body that transmit signals to and from other neurons.Rate this question:
