Oblique plane
Frontal (coronal) plane
Sagittal plane (Correct answer)
Transverse (horizontal) plane

Correct answer: Sagittal plane

The sagittal plane divides the body into left and right sections. The mid-sagittal plane divides it equally, while other sagittal planes may not be symmetrical.

Question 89: How should core concepts and principles knowledge be maintained and updated?

Knowledge updates are only needed every five years
Learning stops after certification
Initial training provides lifelong competence
Through continuous professional development, current literature review, and professional networking (Correct answer)

Correct answer: Through continuous professional development, current literature review, and professional networking

Professional competence requires ongoing development through education, literature review, and engagement with the professional community.

Question 90: Which of the following glands is associated with thermoregulation?

Eccrine glands (Correct answer)
Ceruminous glands
Apocrine glands
Sebaceous glands

Correct answer: Eccrine glands

Eccrine glands are the most abundant type of sweat glands found throughout the body, particularly on the palms, soles, and forehead. Their main role is thermoregulation, as they produce a watery sweat that evaporates from the skin surface, effectively cooling the body. This makes them crucial for maintaining a stable internal body temperature.

Question 91: Cardiac output is calculated by multiplying:

Heart rate × stroke volume (Correct answer)
End-diastolic volume − end-systolic volume only
Blood pressure ÷ heart rate
Stroke volume ÷ heart rate

Correct answer: Heart rate × stroke volume

Cardiac output (CO) = Heart rate (HR) × Stroke volume (SV), representing the volume of blood pumped by the heart per minute.

Question 92: How should communication and documentation knowledge be maintained and updated?

Initial training provides lifelong competence
Learning stops after certification
Through continuous professional development, current literature review, and professional networking (Correct answer)
Knowledge updates are only needed every five years

Correct answer: Through continuous professional development, current literature review, and professional networking

Professional competence requires ongoing development through education, literature review, and engagement with the professional community.

Question 93: Which hormone is primarily responsible for ovulation in females?

Follicle-stimulating hormone (FSH)
Progesterone
Estrogen
Luteinizing hormone (LH) (Correct answer)

Correct answer: Luteinizing hormone (LH)

A surge in LH triggers ovulation, the release of an egg from the ovary. Estrogen and FSH help develop the follicle, and progesterone maintains the uterine lining after ovulation.

Question 94: Which organ is the primary site for T-cell maturation?

Lymph nodes
Spleen
Bone marrow
Thymus (Correct answer)

Correct answer: Thymus

T-cells mature in the thymus, where they are educated to recognize self and non-self cells. Bone marrow produces T-cell precursors, but maturation occurs in the thymus.

Question 95: What is the primary function of the testes in males?

Production of seminal fluid
Transport of sperm
Storage of sperm
Production of sperm and testosterone (Correct answer)

Correct answer: Production of sperm and testosterone

The testes are the male gonads responsible for producing sperm (spermatogenesis) and the hormone testosterone, which regulates male secondary sexual characteristics.

Question 96: The Frank-Starling law of the heart states that:

Increased heart rate always decreases stroke volume
Cardiac output remains constant regardless of changes in preload
Decreased preload increases myocardial contractility
The heart contracts more forcefully as ventricular filling (preload) increases (Correct answer)

Correct answer: The heart contracts more forcefully as ventricular filling (preload) increases

The Frank-Starling law describes how greater ventricular filling stretches cardiac muscle fibers, resulting in a more forceful contraction and larger stroke volume.

Question 97: Where does fertilization of an egg typically occur?

Ovary
Cervix
Fallopian tube (Correct answer)
Uterus

Correct answer: Fallopian tube

Fertilization usually occurs in the fallopian tube (also called the uterine tube or oviduct). The fertilized egg then travels to the uterus for implantation.

Question 98: Which structure in the male reproductive system is responsible for storing and maturing sperm?

Vas deferens
Seminal vesicle
Prostate gland
Epididymis (Correct answer)

Correct answer: Epididymis

The epididymis, located on the back of the testes, stores sperm and allows them to mature and gain motility before being transported through the vas deferens.

Question 99: What is the foundational principle of core concepts and principles in the Anatomy and Physiology field?

Maximizing personal advancement
Following the easiest path available
Avoiding all challenging situations
Maintaining competence, integrity, and service to stakeholders (Correct answer)

Correct answer: Maintaining competence, integrity, and service to stakeholders

The foundational principles of core concepts and principles in Anatomy and Physiology center on maintaining competence, integrity, and quality service.

Question 100: How should applied methods and techniques knowledge be maintained and updated?

Through continuous professional development, current literature review, and professional networking (Correct answer)
Initial training provides lifelong competence
Learning stops after certification
Knowledge updates are only needed every five years

Correct answer: Through continuous professional development, current literature review, and professional networking

Professional competence requires ongoing development through education, literature review, and engagement with the professional community.
