Question 1

What type of joint are the costal cartilages?

a. Primary cartilaginous
b. Secondary cartilaginous
c. Synovial
d. Fibrous
e. Condyloid

Answer 1

a. primary cartilagenous

Bone are connected via hyaline cartilage

Question 2

What type of joint is the distal tibio-fibular joint?

a. Primary cartilaginous
b. Secondary cartilaginous
c. Synovial
d. Fibrous
e. Condyloid

Answer 2

d. fibrous

is a syndemoses = little movement

Question 3

where else can you find hyaline cartilage?

a. Epiglottis
b. Bronchioles
c. External ear (auricle)
d. Bronchi
e. Meniscus of the knee joint

Answer 3

d. trachea + bronchi
epiglottis + external ear = elastic
bronchioles = no cartilage
meniscus of knee = fibrocartilage

a. Appendix
b. Ascending colon
c. Distal 1/3 of transverse colon
d. 3rd and 4th parts of the duodenum

Question 7

What are the 4 layers of the gastrointestinal tract, from innermost to outermost?

a. Serosa, muscularis propria, submucosa, mucosa
b. Submucosa, mucosa, muscularis propria, serosa
c. Mucosa, submucosa, muscularis propria, serosa
d. Submucosa, mucosa, serosa, muscularis propria
e. Mucosa, muscularis propria, submucosa, serosa

Answer 7

C. Mucosa, submucosa, muscularis propria, serosa

The submucosa contains larger blood vessels, nerves, lymphatics, mucus secreting glands etc. Muscularis propria – there is an inner circular and outer longitudinal muscle layer. The serosa is also known as the adventitia and usually covers external surfaces.

Question 8

What are the true vocal cords lined by?

a. Pseudostratified ciliated columnar epithelium
b. Stratified squamous epithelium
c. Simple squamous epithelium
d. Simple columnar epithelium
e. Stratified cuboidal epithelium

Answer 8

B. stratified squamous epithelium.

As they constantly adduct and vibrate during phonation, SSE is better suited to the constant sloughing.

Question 9

which laryngeal muscle is responsible for normal breathing?

a. Posterior cricoarytenoid muscle
b. Lateral cricoarytenoid muscle
c. Interarytenoid muscle
d. Thyroarytenoid muscle
e. Cricothyroid muscle

Answer 9

A. Posterior cricoarytenoid muscle

It is the only abductor of the vocal cords.

Question 10

What is the epithelium that lines the airways?

a. Goblet cells
b. Ciliated pseudo stratified columnar epithelium
c. Ciliated stratified columnar epithelium
d. Ciliated cuboidal epithelium
e. Macrophages

Answer 10

B. Ciliated pseudo stratified columnar epithelium

Question 11

Which lobe is an aspirated peanut most likely to have entered?

a. Right lower lobe
b. Left lower lobe
c. Right middle lobe
d. Left upper lobe
e. Right upper lobe

Answer 11

A – Right lower lobe.
As the right bronchus is slightly wider and more vertical aspirated objects tend toward the right lung. Assuming the man is standing up the peanut will most likely enter the lower lobe due to gravity.

Question 12

The expiratory reserve volume is:

a. The volume in the lungs at the end of passive expiration
b. The maximal volume of air that can be forcibly exhaled following a normal expiration
c. The volume of air remaining in the lungs after a maximal exhalation
d. The volume of air moved into or out of the lungs during quiet breathing
e. The maximal volume that can be inhaled from the end-inspiratory level

Answer 12

B. The maximal volume of air that can be forcibly exhaled following a normal expiration

Question 13

Which neurotransmitter is particularly active in the substatnia nigra?

a. Serotonin
b. Glutamate
c. Acetylcholine
d. Dopamine
e. Noradrenaline

Answer 13

D. Dopamine

Question 14

Which of the following structures is not included in the basal ganglia?

a. Subthalamic nucleus
b. Globus pallidus
c. Thalamus
d. Caudate nucleus
e. Putamen

Answer 14

C. Thalamus

Question 15

What structure mainly forms the roof of the fourth ventricle?

a. Cerebellum
b. Tentorium
c. Corpus callosum
d. Thalamus
e. Internal capsule

Answer 15

A – Cerebellum mostly forms the roof of the fourth ventricles.
Remember for the foramina of the 4th ventricle magendie = medial, luschka = lateral

Question 16

What is shown in the slide above?

a. Graafian follicle
b. Proliferative endometrium
c. Corpus luteum
d. Cervical lining
e. Vaginal epithelium

Answer 16

C – Corpus luteum.
If fertilisation and implantation take place the corpus luteum will continue to secrete progesterone and small amounts of oestrogen for around 4 weeks until the growing placenta takes over.

Question 17

Which hormone(s) is/are required for proliferative endometrium to become secretory endometrium?

a. Progesterone
b. Follicle stimulating hormone
c. Oestrogen
d. Progesterone and oestrogen
e. Lutenising hormone

Answer 17

D. In the proliferative phase, the uterine lining and uterine glands become thicker as epithelial and stromal cells undergo mitosis. This phase is under oestrogen control. Oestrogen causes upregulation of oestrogen receptors (thus enhancing its own effect) and progesterone receptors, to prime the endometrium and enable it to respond to progesterone in the luteal phase.

Question 18

Which of the following structures runs through the inguinal canal in women?

a. Broad ligament
b. Vaginal artery
c. Ovarian ligament
d. Ilioinguinal nerve
e. Round ligament

Answer 18

– The round ligament, which passes through the inguinal canal to the labia majora where its fibres attach to the mons pubis. The ilioinguinal nerve passes through the superficial inguinal ring but not the deep inguinal ring, so doesn’t go through the whole inguinal canal.

Question 19

. The juxta-glomerular apparatus releases a hormone. What is the function of this hormone?

a. It catalyses the conversion of angiotensin I to angiotensin II
b. It converts 25-hydroxyvitamin D to 1, 25-dehydroxyvitamin D
c. It causes the release of aldosterone
d. It catalyses the conversion of angiotensinogen to angiotensin I
e. It stimulates the release glucocorticoids from the adrenal glands

Answer 19

D. Angiotensin converting enzyme converts angiotensin I to angiotensin II.

Question 20

Which parasympathetic nerve is responsible for micturition?

a. Pudendal nerve
b. Ilioinguinal nerve
c. Genitofemoral nerve
d. Pelvic splanchnic nerve
e. Hypogastric nerve

Answer 20

Answer: D – Pelvic splanchnic nerve, which causes contraction of the detrusor muscle and relaxation of the internal sphincter. The hypogastric nerve is responsible for the sympathetic innervation which relaxes the detrusor muscle and causes contraction of the internal sphincter therefore allowing storage of urine. The pudendal nerve is related to control of the external urethral sphincters and is under somatic control. The genitofemoral nerve and ilioinguinal nerve innervate the areas around the genitals and groin.
