Explanation:

• Question 73: The iliacus is a hip - flexor muscle and not involved in breathing. The diaphragm is the main muscle of respiration, the scalene muscles assist in inhalation by elevating the first two ribs, and the intercostal muscles (external and internal) help in the expansion and contraction of the thoracic cavity during breathing.
• Question 74: The prefix "angio - " refers to blood vessels and "plasty" means repair. So, angioplasty is the surgical repair of a blood vessel. Surgical excision of a vein is phlebectomy, suturing of a blood vessel is angiorrhaphy, and surgical fixation of the spleen is splenopexy.
• Question 75: Alzheimer's Disease is characterized by early senility, confusion, loss of recognition of persons or familiar surroundings, and restlessness.
