During the monthly cycle, what role does Follicle Stimulating Hormone (FSH) play? Maintains the uterine lining for potential pregnancy Inhibits the production of estrogen Stimulates the tertiary follicle to grow and bulge out of the ovary Triggers the release of the oocyte from the ovary

Stimulates the tertiary follicle to grow and bulge out of the ovary

What is the function of Luteinizing Hormone (LH) during the menstrual cycle? Initiates the growth of the uterine lining Causes the corpus luteum to form Prompts the oocyte to finish meiosis Stimulates the production of progesterone

Prompts the oocyte to finish meiosis

What is ovulation, and what key processes occur during this phase? The shedding of the uterine lining When the follicle bursts and the oocyte moves to the uterine tube The formation of the corpus luteum The repair of the functional layer of the uterus

When the follicle bursts and the oocyte moves to the uterine tube

What occurs after ovulation in the menstrual cycle? The oocyte is fertilized The remnants of the follicle form the corpus luteum The basal layer of the uterus repairs The uterine lining begins to shed

The remnants of the follicle form the corpus luteum

What eventually happens to the corpus luteum if pregnancy does not occur? It transforms into a new follicle It is absorbed back into the ovary It continues to produce hormones indefinitely It degrades into scar tissue called corpus albicans

It degrades into scar tissue called corpus albicans

How long does the uterine cycle typically last, and what are some key characteristics? 35 days, with extended secretory phase 21 days, with phases including ovulation and luteal 28 days, with phases including menstrual, proliferative, and secretory 14 days, with only a menstrual phase

28 days, with phases including menstrual, proliferative, and secretory

What are the three phases of the uterine cycle? Menstrual, proliferative, secretory Pre-ovulatory, ovulatory, post-ovulatory Initial, middle, final Follicular, ovulatory, luteal

Menstrual, proliferative, secretory

What is the function of the internal jugular vein in the human circulatory system? Receives the bulk of blood draining from the brain, the largest of the paired veins draining from the head and neck Collects blood from the spleen and parts of the stomach Drains blood from the superficial scalp and face structures Drains the entire small intestine and part of the large intestine

Receives the bulk of blood draining from the brain, the largest of the paired veins draining from the head and neck

Describe the great saphenous vein and its significance in medical procedures. Runs along the lateral aspect of the foot and through the calf muscle Drains the digestive viscera and transports venous blood to the liver Drains the distal portions of the large intestine and rectum The longest vein in the body, commonly used as a coronary bypass vessel, travels superiorly along the medial aspect of the leg to the thigh, where it empties into the femoral vein

The longest vein in the body, commonly used as a coronary bypass vessel, travels superiorly along the medial aspect of the leg to the thigh, where it empties into the femoral vein

What is the role of the superior vena cava in the circulatory system? Receives systemic blood draining from all areas superior to the diaphragm except the heart wall, formed from the right and left brachiocephalic veins, and empties into the right atrium Returns blood to the heart from all body regions inferior to the diaphragm Drains the distal portions of the large intestine and rectum Drains the entire small intestine, part of the large intestine, and stomach

Receives systemic blood draining from all areas superior to the diaphragm except the heart wall, formed from the right and left brachiocephalic veins, and empties into the right atrium

Where do the common iliac veins join, and what do they form? Join the brachial vein in the axilla to form the axillary vein Join at L5 to form the distal end of the inferior vena cava Join the superior mesenteric vein to form the hepatic portal vein Join the splenic vein just before the vessel unites with the superior mesenteric vein

Join at L5 to form the distal end of the inferior vena cava

What is the significance of the median cubital vein in medical procedures? Crosses the anterior aspect of the elbow, commonly used to obtain blood samples or administer intravenous medications, connects the basilic and cephalic veins Drains the entire small intestine, part of the large intestine, and stomach Runs along the lateral aspect of the foot and through the calf muscle Drains the digestive viscera and transports venous blood to the liver

Crosses the anterior aspect of the elbow, commonly used to obtain blood samples or administer intravenous medications, connects the basilic and cephalic veins

What structures does the external jugular vein drain, and where does it empty? Drains superficial scalp and face structures served by the external carotid arteries, passes over the sternocleidomastoid muscle and empties into the subclavian veins Receives the bulk of blood draining from the brain Collects blood from the spleen and parts of the stomach Drains the entire small intestine and part of the large intestine

Describe the pathway of the basilic veins in the arm. Drains the distal portions of the large intestine and rectum Runs along the posteromedial aspect of the forearm, crosses the elbow, and then joins the brachial vein in the axilla to form the axillary vein Runs along the lateral aspect of the foot and through the calf muscle Drains the digestive viscera and transports venous blood to the liver
