Describe the anatomy of spine, bones, nerves and muscles.

Expert Solution

Spine - Thr human spine is mainly divident into three parts which are cervical, thoracic and lumbar. These contains 33 individual bones interlock and gives structure of spinal cord. The spine olay a major role in coorfinating the reflexes and giving posture to body.

Bone - basically bone is an hard material made of osseous tissue. The bone consists of calcaleous which is covered by periosteum and have inner bone marrow. Bones help for movement and gives posture for body.

Nerves - generally nerves are 3 types based on their function which are sensory, motor and autonimic. The nerve contain many axons, perineurium, endoneurium, endoneural fluid and epineurium. These nerves help to carry motor and sensory information to and from the central nervous system and spinal cord.

Muscles - Muscles are about 700 in number which attach to bone and aids in movement each muscle have their tissue, blood vessels, nerve. Sarcomeres are the basic functional units of muscles containing actin and myosin filaments responsible for muscle contraction.

In a comparative Anatomy lab, you found some bones and the jaws are toothed and that the anterior limbs are modified for flight. Determine whether this tetrapod is related phylogenetically to the subclass Archosauria of the Reptilia, to either the subclass Archaeornithes or the Neornithes of the Aves or to the subclass Eutheria of the Mammalia. Describe those aspects of the fossil which allows you to make your determination. IN OTHER WORDS, WHICH OF THE ABOVE ANIMALS POSSESS THE FEATURE,...

Written Assignment: Using an anatomy atlas, detail the pathways of the six cranial nerves that govern suck-swallow-breathe. I want to know from where they originate, to their pathways through the various foramina and where they end. Are the pathways sensory or motor? If motor, what muscles do they innervate; if sensory, into which nucleus do they terminate? Instructions: You may do algorithms diagrams; write out the pathways as if writing an essay; create graphics, etc. I want to know where...
