Answer 1

Q31: Spinal Nerve contains sensory and motor fibers.

Spinal nerve is known to be mixed nerve by the composition which carries motor, sensory, and autonomic signals between the spinal cord and the body.

Q32: A sarcomere gets shorter when contracts.

Q33: The tectorial membrane converts sound waves in the atmosphere to chemical impulses.

The tectorial membrane (TM) is an extracellular connective tissue that covers the mechanically sensitive hair bundles of the sensory receptor cells in the inner ear. It occupies a strategic position, playing a key role in transforming sound to mechanical stimulation.

Q34: The carpals are the Wrist bones.

Eight small bones of the wrist that connects hand to forearm.

Q35: The type of cells that take calcium from the blood are Osteoblasts and the type of cells that deposit calcium into the blood are Osteoclasts.

One very important function of bone is to send calcium into the bloodstream when the body needs it. Specialized cells called osteoclasts break down bone to free the calcium. Cells that are known as osteoblasts deposit calcium into bone, remaking it.

Q36: Tibialis anterior is located at lower limb.

The tibialis anterior muscle is a long, narrow muscle in the anterior compartment of the lower leg. It originates along the lateral condyle and proximal body of the tibia, it runs down the shin just lateral to the tibia. Just above the ankle, the muscular body of the tibialis anterior ends and its long tendon extends across the medial side of the ankle and into the foot.

Q37: The correct statement is: The zygomatic bone is the cheek bone.

Mandible is the lower jaw bone and mandible is the only moveable facial bone. The sternum is not irregular bone. Irregular bones are different in size and shape and usually very compact. Examples include vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella.

Q38: The hormone that acts in direct opposition to insulin is Glucagon and causes the Increase in the blood glucose level.

Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It works to raise the concentration of glucose in the bloodstream whereas insulin decreases the blood glucose level.

Q39: Cones functions in bright light and in color vision.

Cones reside mostly in the central portion of the retina, and aid in visualizing in bright light with fine visual detail and color.

Q40: The pancreas secretes insulin and glucagon.

Melatonin is produced by pineal gland in animals and thymosin is supposed to be mainly produced by thymus.
