MLT GlobeAnatomy: General anatomy & terminology
25 Anatomy MCQs on General anatomy & terminology with answers and explanations.
A pathologist studying the causes and patterns of congenital malformations works in which field?
Teratology deals specifically with abnormal development and birth defects. Embryology covers normal prenatal development, so it is the tempting but broader choice.
Interpreting body structures on X-ray films, CT and similar images falls under which branch of anatomy?
Radiological anatomy studies structure using imaging such as X-rays. Surface anatomy relates internal structures to external landmarks without imaging.
What is the smallest unit that can carry out all life processes independently?
The cell is the basic unit of life. Organelles cannot survive alone, while tissues and organs are higher levels built from many cells.
Which of these is NOT considered a transport system of the body?
Blood, lymph and the cardiovascular system move substances around the body. The nervous system communicates by electrical impulses, not bulk transport.
A vertical plane parallel to the midline that divides the body into unequal right and left parts is the:
The median plane gives equal halves; any parallel sagittal plane off the midline is parasagittal and gives unequal halves.
Turning the sole of the foot to face medially is called:
Inversion turns the sole inward; eversion turns it outward. Plantar flexion points the toes downward.
In anatomical terms, the thumb is ______ to the little finger when the hand is in anatomical position.
In anatomical position the palms face forward, so the thumb lies farther from the midline (lateral). 'Medial' means nearer the midline.
The brachial artery is so named because 'brachial' refers to the:
'Brachial' means relating to the arm; blood pressure is measured over the brachial artery. 'Umbilical' refers to the navel, 'crural' to the leg.
Which is NOT one of the nine regions of the abdomen?
The nine regions include hypochondriac, epigastric, lumbar, umbilical, iliac and hypogastric. The diaphragm is a muscle forming the upper boundary.
A lesion causing weakness on the same side of the body as the lesion is described as:
Ipsilateral means on the same side; contralateral means the opposite side; bilateral means both sides.
A CT slice that separates the body into front and back portions lies in which plane?
The coronal plane divides the body into anterior and posterior parts. Sagittal planes divide left and right; transverse planes divide upper and lower.
Which of these is NOT one of the four primary tissue types?
The four basic tissues are epithelial, connective, muscle and nervous. Lymphoid tissue is a specialized form of connective tissue.
An enlarged spleen is felt under the left costal margin. In which abdominal region does the spleen lie?
The spleen lies in the left hypochondriac region beneath ribs 9–11. It is not normally palpable unless enlarged.
What is the approximate mean oral body temperature of a healthy adult?
Normal core temperature averages about 37 °C (range roughly 36.5–37.5 °C). Values near 39–40 °C indicate fever; 35 °C indicates hypothermia.
In human anatomy, a structure described as ventral lies on which aspect of the body?
In the anatomical position, ventral and anterior both mean toward the front; dorsal equals posterior.
The perineal region between the thighs is made up mainly of:
The perineum consists of muscles (such as the perineal body attachments), fibrous connective tissue and fat, supporting the pelvic outlet.
A textbook chapter on splanchnology would describe which structures?
Splanchnology is the study of the viscera. Osteology covers bones, myology muscles and neurology nerves.
Which plane divides the body into equal right and left halves?
The midsagittal plane passes vertically through the midline creating equal right and left halves. A coronal plane separates front from back.
The developing human is called an embryo until the end of which period?
The embryonic period lasts to the end of week 8, during which organs form. From week 9 until birth it is called a fetus.
Which primary tissue has cells scattered in abundant extracellular matrix of fibres and ground substance?
Connective tissue is defined by abundant extracellular matrix. Epithelium consists of closely packed cells with little matrix.
