Question

28. ___ is a hormone released from the kidneys due to a drop in blood pressure.
29. The function of ___ from the kidney is to stimulate red blood cell production in the bone marrow.

30. ___ is the primary process occurring within the proximal convoluted tubules that allows for the return of fluids and nutrients to the body.

31. The ___ is the bone of the arm.
32. ___ is an excessive lateral curvature of the vertebral column.

33. The bones of the skull are divided into two groups: the facial bones that help form facial features and the ___ bones that form a part of the protective casing for the brain.

34. ___ are the muscles responsible for movement in the desired direction.
35. The ___ of a muscle is the end that is attached to a movable bone.
36. Muscle ___ is the degree to which a resting muscle resists passive movements.

Answer 1

28 Angiostensin

• Among other functions of kidneys, another function is production of hormones.
• Hormones renin and angiotensin, regulated salt balance.
• Renin converts angiotensinogen to angiotensin-I.
• Angiotensin converting enzyme converts angiotensin-I to angiotensin-II.
• Angiotensin-II results in increased blood vessel constriction and elevates blood pressure.

29. Erythropoietin

• Hormone erythropoietin stimulate bone marrow to produce red blood cells.

30. Reabsorption

• Proximal convoluted tubule: PST is proximal portion of nephron duct system, from the Bowman’s capsule to the loop of Henle’s.
• They are present in renal cortex.
• They are made of cubodoil epithelium, which help in reabsorption process.

31. Humerus

• The large bone humerus joins to shoulder socket.

32. Scoliosis

• Scoliosis is a condition of excessive lateral curvature in vertebral column.
• The curvature may be in “C” or “S” shape.

33. Cranium

• The skull bones are subdivided as:

1. Cranium or neurocranium- formed by 8 bones. 2 bones form the roof or Calvarium and base is formed by 6 bones.
2. The face bones- 14 bones comprises of the face.

34. Skeletal muscles

The skeletal muscles are attached to skeleton and helps in voluntary movement.

35. Insertion

The muscle part or end which is attached to the movable structures and help in movement

36. Muscle tone

Muscle tone is the passive resistance exhibited by resting muscle, towards stretch. Also referred to as the degree of residual contraction.
