HESI A2 Version 1 Anatomy and Physiology Questions
Question 1 of 5
What substance makes up the pads that provide support between the vertebrae?
Correct Answer: B
Rationale: Cartilage is the substance that makes up the pads providing support between the vertebrae. These pads, known as intervertebral discs, consist of tough outer layers of fibrous cartilage and a gel-like inner core. Cartilage plays a crucial role in cushioning the vertebrae, absorbing shock, and maintaining flexibility in the spine.
Question 2 of 5
Which type of cholesterol is considered to be the healthiest?
Correct Answer: B
Rationale: High-Density Lipoprotein (HDL) cholesterol is considered the healthiest type of cholesterol because it helps remove LDL cholesterol from the arteries, reducing the risk of heart disease. HDL acts as a scavenger, carrying cholesterol away from the arteries to the liver where it can be processed and eliminated from the body. Having high levels of HDL cholesterol is associated with a lower risk of cardiovascular diseases.
Question 3 of 5
Nerve tissue is composed of neurons and connective tissue cells that are referred to as which of the following?
Correct Answer: B
Rationale: Nerve tissue is made up of neurons that transmit signals and neuroglia cells that support and protect the neurons. Neuroglia cells play a crucial role in providing structural support, insulation, and nutrients to neurons. Osteoblasts are bone-forming cells, osteocytes are mature bone cells, and arterioles are small arteries that carry blood away from the heart. Therefore, the correct answer is option B, Neuroglia.
