Explanation / Answer
Answer:
6). A. The two parietal bones
The tow parietal bones (left and right) are separated by the sagittal structure. The frontal and parietal bones are separated by the coronal structure. The occipital and parietal bones are separated by the lambdoid structure.
7). E.all of the above
All glands of the body are constructed of epithelialcells as are the ducts that connect the exocrine types to body surfaces. As linings in the alveoli (air sacs), kidneys, and blood vessels, simple squamous types assist in diffusion, osmosis and filtration phenomena.
8). E. 60
9). D.inhibitory
10). A. Dura meter
The meninges (from the Greek meninx, meaning “membrane”) cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer coveringthe central nervous system.
