The inferior third of this border is raised into a slight ridge, the medial supracondylar ridge, which became very prominent below; it presents an anterior lip for the origins of the brachialis muscle and the pronator teres muscle, a posterior lip for the medial head of the triceps brachii muscle, and an intermediate ridge for the attachment of the medial intermuscular septum. The Deltoid tuberosity is a roughened surface on the lateral surface of the shaft of the Humerus and acts as the site of insertion of deltoideus muscle. The posterorsuperior part of the shaft has a crest, beginning just below the surgical neck of the humerus and extends till the superior tip of the deltoid tuberosity. This is where the lateral head of triceps brachii  is attached. The radial sulcus, also known as the spiral groove is found on the posterior surface of the shaft and is a shallow oblique groove through which the radial nerve passes along with deep vessels. This is located posteroinferior to the deltoid tuberosity. The inferior boundary of the spiral groove is continuous distally with the lateral border of the shaft. The nutrient foramen of the humerus is located in the anteromedial surface of the humerus. The nutrient arteries enter the humerus through this foramen. Distal humerus
The distal or lower extremity of the humerus is flattened from before backward, and curved slightly forward; it ends below in a broad, articular surface, which is divided into two parts by a slight ridge.
Quinapril, sold under the brand name Accupril among others, is a medication used to treat high blood pressure (hypertension), heart failure, and diabetic kidney disease. It is a reasonable initial treatment for high blood pressure. It is taken by mouth.Common side effects include headaches, dizziness, feeling tired, and cough. Serious side effects may include liver problems, low blood pressure, angioedema, kidney problems, and high blood potassium. Use in pregnancy and breastfeeding is not recommended. It is an ACE inhibitor and works by decreasing renin-angiotensin-aldosterone system activity.Quinapril was patented in 1980 and came into medical use in 1989. It is available as a generic medication. In 2019, it was the 294th most commonly prescribed medication in the United States, with more than 1 million prescriptions. Medical uses
Quinapril is indicated for the treatment of high blood pressure (hypertension) and as adjunctive therapy in the management of heart failure. It may be used for the treatment of hypertension by itself or in combination with thiazide diuretics, and with diuretics and digoxin for heart failure. Contraindications
Pregnancy
Impaired renal and liver function
Patients with a history of angioedema related to previous treatment with an ACE inhibitor
Hypersensitivity to quinapril

Side effects
Side effects of quinapril include dizziness, cough, vomiting, upset stomach, angioedema, and fatigue. Mechanism of action
Quinapril inhibits angiotensin converting enzyme, an enzyme which catalyses the formation of angiotensin II from its precursor, angiotensin I. Angiotensin II is a powerful vasoconstrictor and increases blood pressure through a variety of mechanisms.
