(T/F) Ligaments and connective tissue provide dynamic stability to joints when actively contracting.
False; "Ligaments and connective tissue provide static stability to joints" (pg. 19)
(T/F) During the process of bone remodeling, osteoblasts resorb existing bone and osteoclasts form new bone.
False; "New bone is formed by specialized cells known as osteoblasts, whereas the cells that resorb old bone are osteoclasts" (pg. 13)
(T/F) About 50 to 60 percent of the volume of cortical bone is porous.
False; Cortical bone is harder and more compact, with only about 5% to 30% of its volume being porous, with nonmineralized tissue (pg. 14)
There are approximately 552 skeletal muscles in the human body.
