The brain is not a muscle, but it does play a role in muscle control. The brain communicates with the body through the spinal cord and twelve pairs of cranial nerves. Ten of these pairs control hearing, eye movement, facial sensations, taste, swallowing and movement of the face, neck, shoulder and tongue muscles. The brain also contains blood vessels and nerves, including neurons and glial cells.

The brain is not a muscle but it does control muscles in the body
The brain is not a muscle, but it does control muscles in the body. It weighs about 3 pounds in the average adult, and is about 60% fat. The remaining 40% is a combination of water, protein, carbohydrates and salts.
The brain contains blood vessels and nerves, including neurons and glial cells. Gray and white matter are two different regions of the central nervous system. Gray matter is the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: the white matter is on the outside, and the gray matter sits within. Gray matter is primarily composed of neuron somas (the round central cell bodies), and white matter is mostly made of axons (the long stems that connect neurons together) wrapped in myelin (a protective coating). There are close to 86 billion nerve cells (neurons) in the human brain and an equal amount of non-neuronal glial cells.
The brain communicates with the body through the spinal cord and twelve pairs of cranial nerves. Ten of the twelve pairs of cranial nerves that control hearing, eye movement, facial sensations, taste, swallowing and movement of the face, neck, shoulder and tongue muscles originate in the brainstem. The cranial nerves for smell and vision originate in the cerebrum. The basal ganglia, deep within your cerebrum, regulate your movement. The basal ganglia also work with the cerebellum to coordinate fine motions, such as fingertip movements.

The brainstem controls the movement of the face, neck, shoulder and tongue muscles
The brain itself is not a muscle, but it does control the muscles in the body. The brainstem is responsible for controlling the movement of the face, neck, shoulder and tongue muscles. Ten of the twelve pairs of cranial nerves that control these movements originate in the brainstem.
The brain has 12 cranial nerves in total, which carry messages by sending electrical impulses back and forth between the brain, organs and muscles. The brain communicates with the body through the spinal cord and these cranial nerves.
The brain is made up of two tissues, known as grey and white matter. Grey matter is the darker, outside section (the cerebral cortex) that helps with day-to-day functioning, such as muscle control, using the senses, remembering things, experiencing emotions and speech. White matter is the lighter section below the grey matter that sends signals to different parts of the central nervous system.
The basal ganglia, located deep within the cerebrum, also play a role in regulating movement. They work with the cerebellum to coordinate fine motions, such as fingertip movements.

The brain contains blood vessels and nerves, including neurons and glial cells
The brain is not a muscle, but an organ. It does contain a little bit of muscle, but it is mostly made up of a network of grey and white matter. The brain is the centre of the nervous system, and it integrates all sensory data through its cells, known as neurons. These neurons allow the brain to communicate with every organ in the body. The brain is also cushioned and protected by 125ml of cerebrospinal fluid, which allows it to float around. This fluid gives the brain a comfortable ride as you go through your day.
The brain's blood vessels are responsible for supplying oxygen and nutrients to the brain and removing waste products. They are also involved in regulating body temperature and maintaining the proper pH balance in the brain. The blood vessels in the brain are highly specialised, with a unique structure that allows them to respond quickly to changes in the body.
The brain is an incredibly complex organ, with a vast network of cells and blood vessels working together to allow us to function. While it may not be a muscle, the brain shares some similarities with muscles, such as the ability to be trained and strengthened through exercise. However, the brain's primary function is not as an engine for the body, but rather as a control centre for all of our thoughts, feelings, and movements.
