WebThe skeletal system plays a vital role in locomotion and movement. The coordinated movement of skeletal muscles, bones, and ligaments helps in locomotion. It imparts protection to the internal organs that are delicate such as the spinal cord, Human brain, and the lungs. It assists the body in the locomotory movements from one place to another. WebThe radula is a synapomorphy of all molluscs, with only the bivalves having lost this character during phylogeny (Aldrich et al. 1971). The radula is located in the buccal cavity and consists of regular rows of chitinous teeth. The radula is movable using muscular and hydrostatic power (Young 1994; Messenger & Young 1999). In molluscs ...
