Either way, is the spinal cord an organ or organ system?
Major Organ Systems
SystemOrgans in the System
|Cardiovascular||Heart Blood vessels (arteries, capillaries, veins)|
|Respiratory||Nose Mouth Pharynx Larynx Trachea Bronchi Lungs|
|Nervous||Brain Spinal cord Nerves (both those that carry impulses to the brain and those that carry impulses from the brain to muscles and organs)|
Therefore, what system is the brain and spinal cord part of? The base, or lower part, of the brain is connected to the spinal cord. Together, the brain and spinal cord are known as the central nervous system (CNS). Many nerves send electrical signals to and from the brain and spinal cord.
On top of this, what is the main function of the spinal cord?
The brain and spinal cord are your body's central nervous system. The brain is the command center for your body, and the spinal cord is the pathway for messages sent by the brain to the body and from the body to the brain.
What are the 2 parts of the peripheral nervous system?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

The spinal cord and the brain together constitute the Central Nervous System. It is an incredibly complex and intricate mesh of nerves. Functioning as the body's main relay station, the CNS is responsible for all the basic functions of the body, such as breathing, walking, talking, movement, and reflexes.
Unlike tissue in the peripheral nervous system, that in the central nervous system (the spinal cord and brain) does not repair itself effectively.
The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.
Brain is housed inside the skull and it controls most of the activities of the body. In higher organisms such as humans and other vertebrates, it is the centre of learning. Spinal Cord is a tube-like structure that begins from the end of the brain and ends at the bottom of the backbone.
The brain and spinal cord are protected by bony structures â€” the skull and spinal column. Meninges are membranes that cover and protect the brain and spinal cord. There are three layers of meninges: Dura mater, which is closest to the bone.
The main functions of the spinal cord are:
- To conduct reflexes below the neck.
- To conduct messages from the skin and muscles to the brain.
- To conduct commands from the brain to muscles of the trunk and limbs.
The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex. It is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes.
Sensory, motor, and reflex functions are affected or impeded when the brain can't transmit impulses past the injury site in the spinal cord.
The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in ...
There are three types of peripheral nerves: motor, sensory and autonomic. Some neuropathies affect all three types of nerves, while others involve only one or two.
The spinal cord is a column of nerves that connects your brain with the rest of your body, allowing you to control your movements. Without a spinal cord, you could not move any part of your body, and your organs could not function. This is why keeping your spine healthy is vital if you want to live an active life.
When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.
Your spine, or backbone, is your body's central support structure. It connects different parts of your musculoskeletal system. Your spine helps you sit, stand, walk, twist and bend. Back injuries, spinal cord conditions and other problems can damage the spine and cause back pain.
Symptoms of a Spinal Cord Disorder
- Weakness or paralysis of limbs.
- Loss of sensation.
- Changes in reflexes.
- Loss of urinary or bowel control.
- Uncontrolled muscle spasms.
- Back pain.
Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves.
Emergency signs and symptoms of a spinal cord injury after an accident may include: Extreme back pain or pressure in your neck
, head or back. Weakness, incoordination or paralysis in any part of your body. Numbness, tingling or loss of sensation in your hands, fingers, feet or toes.
Anyone with a spinal cord injury can file a claim for Social Security disability benefits as long as the injury has lasted at least three months and is expected to make it impossible for you to work for at least 12 months.
The spinal cord has a length of 42 to 45 cm, the diameter of the spinal cord is about 2cm. The weight of the spinal cord is approximately 35 gm. Additional Information: - The spinal cord passes through the vertebral canal which is also known as the spinal canal.
The brain and spinal cord are covered by three layers of meninges, or protective coverings: the dura mater, the arachnoid mater, and the pia mater.
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
The nervous system is made up of the central nervous system and the peripheral nervous system: The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
