    In zoology, the openings in the skull are called fenestrae, the most prominent of which is the foramen magnum, where the brainstem goes through to join the spinal cord. In human anatomy , the neurocranium (or braincase), is further divided into the calvarium and the endocranium , together forming a cranial cavity that houses the brain.
