What are the two parts of the nervous system? (2024)

What are the two parts of the nervous system?

The Central and Peripheral Nervous Systems

We can anatomically divide the nervous system into two major regions: the central nervous system (CNS) is the brain and spinal cord, the peripheral nervous system (PNS) is the nerves (Figure 12.1. 1).

What are the 2 physical divisions of the nervous system?

The Central and Peripheral Nervous Systems

We can anatomically divide the nervous system into two major regions: the central nervous system (CNS) is the brain and spinal cord, the peripheral nervous system (PNS) is the nerves (Figure 12.1. 1).

What are the two main nerves in the nervous system?

You have two main types of nerves: Sensory nerves carry signals to your brain to help you touch, taste, smell and see. Motor nerves carry signals to your muscles or glands to help you move and function.

What are the 2 parts of the peripheral nervous system?

What are the parts of the nervous system and its function?

Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions. The brain and spinal cord (the CNS) function as the control center.

Which are the two component parts of the nervous system quizlet?

The Nervous System is divided into two parts. What are they? 1) The CNS (Central Nervous System) and 2) The PNS (Peripheral Nervous System.

What are the two main communication systems of the body?

Humans have two types of communication systems. These are the nervous system and the endocrine (hormone) system. These systems regulate body processes through chemical and electrical signals that pass between cells.

What is the nervous system for dummies?

The nervous system sends messages from nerve endings to the brain and from the brain to cells, tissues, and organs. Cells of the nervous system sometimes secrete chemical messengers instead of neurotransmitters. These specialized nervous system cells are called neurosecretory cells, and they produce neurosecretions.

What is a real life example of a nerve?

For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away.

What is central nervous system?

What Is the Central Nervous System? The central nervous system is made up of the brain and spinal cord: The brain controls how we think, learn, move, and feel. The spinal cord carries messages back and forth between the brain and the nerves that run throughout the body.

What are the 3 parts of the nervous system?

The human nervous system is made up of three basic parts: the central nervous system, the peripheral nervous system, and the autonomic nervous system. Without a doubt, it is the most complex part of the human body, a masterpiece of nature.

What are 3 main things the nervous system does?

The nervous system plays a role in nearly every aspect of our health and well-being. It guides everyday activities such as waking up; automatic activities such as breathing; and complex processes such as thinking, reading, remembering, and feeling emotions.

What is the relationship between the 2 parts of the nervous system?

Answer. The central nervous system controls thoughts and feelings while the peripheral nervous system controls movement. The peripheral nervous system transfers impulses to and from the central nervous system, where the information is processed.

What makes up the nervous system?

The nervous system includes the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is made up of the brain and spinal cord, whereas the PNS is made up of the somatic and autonomic nervous systems.

What are 2 body systems that work together and explain?

For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.

How do you know if something is wrong with your nervous system?

The most common symptoms of a nerve condition include: A feeling of numbness, pain, tingling, or burning in your limbs or extremities. Unexplained weakness, loss of muscle strength, or paralysis. A headache that is persistent, comes on suddenly, or is "different"

What is the main control station of your body?

The brain is the body's “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data. These centers can be subdivided to Lower Centers (including the spinal cord and brain stem) and Higher centers communicating with the brain via effectors.

What would happen if you had no nerves?

Without nerve cells, we wouldn't know if it's dark or light, hot or cold. We wouldn't be able to touch anything or feel if someone is touching us. We wouldn't be able to smell or taste anything and would have no idea that we have an upset stomach or that we have cut ourselves.

What are at least two fun facts about the nervous system?

What are 3 fun facts about the nervous system?

In our central nervous system, there are more than millions of nerve cells, 100 billion neurons in the human brain and about 13,500,000 neurons in the spinal cord. The longest and widest single nerve in the human body is the sciatic nerve.

What is the GREY matter in the brain?

Grey matter is a type of tissue in your brain and spinal cord (central nervous system) that plays a crucial role in allowing you to function normally day to day. It consists of high concentrations of neuronal bodies, axon terminals (endings) and dendrites.

What protects the spinal cord?

A protective layer of bone called the vertebral column covers and protects your spinal cord. The bones in the vertebral column are called vertebrae (plural of one spine bone, a vertebra).

What part of the brain is responsible for stress?

Brain areas implicated in the stress response include the amygdala, hippocampus, and prefrontal cortex. Neurochemical systems, including Cortisol and norepinephrine, play a critical role in the stress response.

What are the 7 functions of the nervous system?

What are the 7 main parts of the central nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).
