Answer:
A brain ventricle is a cavity in the brain with an open channel leading to it.
Explanation:
The brain and spinal cord are encased and protected by three layers of tissue, all called meninges. The outermost layer is called the dura mater, and covers both the brain and spinal cord. On either side of this layer, where it crosses or penetrates into these organs, are two extensions that look like small tubes coming from under a tent. These extensions are called cranial nerves because they come out on either side of the head just below its most prominent part - hence "cranial".

Answer:
The heart is a cone-shaped muscular organ located within the THORAX
. Its apex rests on the DIAPHRAGM , and its base is at the level
of the SECOND rib. The coronary artenes that nourish the
myocardium arise from the AORTA. The coronary sinus empties
into the RIGHT ATRIUM . Relative to the roles of the heart chambers, the
ATRIA are receiving chambers, whereas the VENTRICLES are
discharging chambers. The membrane that lines the heart and
also forms the valve ſaps is called the ENDOCARDIUM , The outermost
layer of the heart is called the EPICARDIUM . The fluid that fills the
pericardial sac acts to decrease FRICTION during heart activity.
The heart muscle, or myocardium, is composed of a special-
ized type of muscle tissue called CARDIAC MUSCLE
