Trachea
Also known as the windpipe; it is a tube which transports air in to the lungs.
Ventricle
A set of four cavities interconnected in your brain that create and circulate cerebral spinal fluid (CSF).
You also have two ventricles, called chambers, in your heart that move blood to and from the heart.

Central Nervous System [CNS]
The central nervous system (CNS) is one of the main parts of the nervous system which is comprised of the brain and spinal cord. It is contained within the skull and spine and is responsible for most functions of the body and mind. It is responsible for taking in sensory information, organizing and synthesizing it and providing instructions for the rest of the body. In addition, controls for higher-level functioning (thought), coordination, respiration and digestion all come from different parts of the central nervous system. The other main part of the nervous system is called the peripheral nervous system (PNS).
caudal
Towards the tail; or in reference to the spine, the sacral spine (near the tailbone).
brainstem
The brainstem is located at the base of the brain between the deep structures of the cerebral hemispheres and cervical spinal cord. It is made up of the medulla oblongata, pons, and midbrain, and it continues downward to form the spinal cord. It controls automatic functions such as breathing, swallowing, heart rate, blood pressure, consciousness, sleeping, reflex control, and vasomotor control. The brainstem connects all parts of the Central Nervous System (CNS). All information between the brain and the rest of the body passes through the brainstem. Also frequently spelled: brain stem.
arachnoid
Middle-layer of delicate membranes which cover the brain and spinal cord; part of the meninges.
Afferent Nerves
Sensory nerves in the Peripheral Nervous System; nerve paths that carry signals from the periphery (the outer edges of the body) to the brain and spinal cord (the central area of the body). In contrast, see: efferent nerves (motor nerves).
Cerebral Tonsils
Two lobes that make up the lowest part of the cerebellum; one at the bottom of each hemisphere.
Many doctors claim that the cerebral tonsils have no function of their own, however damage to either or both have been known to produce symptoms including: dizziness, unsteady gait, poor depth perception, sensations of swaying/floating, nausea or vomiting, fatigue, brain fog, insomnia, loss of memory, aphasia, and becoming easily confused.
Also Known As: Cerebellar Tonsils
