Explanation / Answer

1)in general, stronger the stimulus,the larger resulting receptors and action potential is true because(in relative refractory period stronger stimulus is required to get action potential) 2) the structural classification of joints is based on the composition of the binding materials and presences and absences of a joint cavity it is true. 3)An osteon cpontains osteocytes, lamella, and a central canal, and is found in compact bone only it is true. 4)the periosteum is a tissue that serves only to protect the bone because it is not supplied with nerves or blood cells, it is false, because the periosteum dense fibrous membrane mostly consists of collagen and also contain nerve fibres that cause pain and it also has blood vessels. 5)the optic disc is forms a blind spot in the retina it is true because there are no rods and cones overlying the optic disc it corresponds to a small blind spot in each eye. 6)humans have 10 pairs of ribs it is false because there are 12 pairs of ribs. 7)ciliary body muscles are considered voluntary skeletal muscles false because they are smooth muscles. 8)the function of the lens of the eye is to allow precise focusing of light on the retina is true. 9)the hair cells are mechano receptors that are involved in both body equilibrium and balance and hearing it is true because these cells are present in the semicircle canals of the inner ear. 10)sound is generally perceived in the occipital lobes of cerebral cortex it is false because sound is perceived by frontal lobes. 11)in order for sound to reach the spiral organ, the auditory ossicles must vibrate the oval window and set the endolymph in motion is true. 12)the pitch of a sound is conveyed to the nervous system through the region of the basiliar membrane that is stimulated is true. 13)bones areclassified by whether they are weight bearing or protective in function it is false. 14)the utricle and saccula responds to linear acceleration of the head it is true. 15)the major role of ligaments at synovial joints is to unite bones and prevent undesirable movements it is true. 16)with the body in anatomical position, the radius is medial to ulna it is false because ulna is medial side of the forearm and runs parallel to the radius. 17)the mobility and strength of joints are inversely related characteristics it is true because joints does not posses strength themselves so to strengthen the joints the muscles should be strengthen as muscles surround the joints.
