The ribs (costae) are curved bone plates, flattened laterally and slightly twisted
in length. Each rib consists of a bony part and rib cartilage. The length of the edges

The heart (cor) is a hollow, four-chambered, cone-shaped muscular organ whose
function ensures continuous blood flow through the blood vessels. It is located behind
the sternum in the middle mediastinum of the thoracic cavity.
Synapse (synapsis) is a specialized contact that determines the polarization of a
nerve impulse along a chain of neurons. There are synapses with chemical and electrical
transmission.
The skull (cranium) is the skeleton of the head, serves as a receptacle for the
brain, sensory organs of the initial parts of the digestive and respiratory systems. The
skull is divided into cerebral and internal.
