#13.) What is the function of tendons?
The tendon is a tough, flexible band of
fibrous connective tissue and its main function is connecting muscle tissues to
the bones. When a muscle contracts, it pulls on a bone to cause movement; the
structure that transmits the force of the muscle contraction to the bone is
called a tendon. Tendons can have several shapes ranging from wide and flat,
ribbon and fan shaped.
#38.) Harry was pondering an exam question that said, "What muscle type has elongated cells and is found in the walls of the urinary bladder?" What should he have responded?
The type of muscle that has elongated cells and is found in the walls of the urinary bladder is the smooth muscle. Smooth muscles are found in many areas of the body, including the
urinary tract, reproductive, and
digestive system. Smooth muscles are composed of elongated, spindle shaped cells. Smooth muscles in the bladder are in three layers,
facing in different directions for strength. They allow the bladder to
expand as more urine enters it, and they gently contract to aid
urination when the bladder is voided.
