The brain has three sections on three different levels, from the top to the brain- stem, which form a unit.
The cerebellum is also sometimes called the "Little Brain" or the brain within the brain.
The central nervous system is the brain and spinal cord. The branches from the brain and cord are called the peripheral nervous system.
The fluid filled spaces in the brain are called ventricles. The fluid is called cerebrospinal fluid
The hollow areas within the brain are called ventricles. There are four ventricles in the brain: two lateral ventricles, the third ventricle, and the fourth ventricle. These spaces are filled with cerebrospinal fluid which helps cushion and protect the brain.
The brain has several major branches or structures, including the cerebrum, cerebellum, and brainstem. Each of these branches plays a specific role in regulating different functions such as movement, coordination, sensory processing, and vital bodily functions like breathing and heart rate. These structures work together to ensure the brain functions properly and coordinates communication throughout the body.
The first branches off the trachea are called the bronchi. The trachea divides into two primary bronchi, which further branch out into smaller bronchioles within the lungs.
Within the nervous system. The brain is obviously packed full of them, whilst the spinal cord and all extending peripheral branches are a network of nerve cells to carry signals between the brain and body.
The thick white band of nerves deep within the brain is called the corpus callosum. It connects the two hemispheres of the brain and allows them to communicate with each other.
interneurons also called central or association neurons
Messages move to and from the brain along thin cells called neurons. Neurons transmit electrical and chemical signals that allow for communication within the brain and nervous system.
The profuse branches at the end of axons are called axon terminals or synaptic terminals. These structures contain neurotransmitters that are released to communicate with other neurons or target cells at synapses.
The four hollow and interconnected spaces within the brain are called ventricles. They are filled with cerebrospinal fluid, which helps cushion the brain, supply nutrients, and remove waste products. The ventricles play a crucial role in maintaining the brain's overall health and function.
