- A. Synostosis
- B. Synchondrosis
- C. Diarthrosis
- D. syndesmosis
Explanation: A syndesmosis is a fibrous joint in which adjacent bones are united by a ligament or an interosseous membrane.
Correct answer: syndesmosis- A. Cords of billroth
- B. Hassal's corpuscles
- C. Lymphatic nodules
- D. While pulp
Explanation: The cortex of a lymph node contains lymphatic nodules, including B-cell follicles, while the medulla contains medullary cords and sinuses.
Correct answer: Lymphatic nodules- A. Gomphosis
- B. Enarthroses
- C. Diarthroses
- D. Amphiarthroses
Explanation: Amphiarthroses are slightly movable joints in which bones are joined by fibrocartilage, as in symphyses, or by strong interosseous…
Correct answer: Amphiarthroses- A. Spleen
- B. Kidney
- C. Liver
- D. Small intestine
Explanation: The space of Disse is the perisinusoidal space between hepatocytes and the sinusoidal endothelium in the liver, where exchange of plasma…
Correct answer: Liver- A. Auditory tube
- B. Nasal septum
- C. Articular cartilage
- D. Costal cartilage
Explanation: Elastic cartilage is found in structures needing flexibility, including the auditory tube, epiglottis, and external ear.
Correct answer: Auditory tube- A. Salivary
- B. Mammary
- C. Sebaceous glands
- D. Gastric
Explanation: Sebaceous glands are holocrine glands because the entire secretory cell disintegrates and becomes part of the secretion.
Correct answer: Sebaceous glands- A. Cortical bone
- B. Cancellous bone
- C. Teeth
- D. Nail
Explanation: A Haversian system, or osteon, is the structural unit of compact cortical bone and contains a central canal surrounded by concentric…
Correct answer: Cortical bone- A. Type I
- B. Type II
- C. Type III
- D. Type IV
Explanation: Sutures are fibrous joints containing dense collagen bundles, predominantly type I collagen, which provides strong tensile resistance.
Correct answer: Type I- A. Brain
- B. Posterior pituitary gland
- C. Liver
- D. Small intestine
Explanation: Liver sinusoids are discontinuous capillaries with wide gaps and an incomplete basal lamina, making them more permeable than ordinary or…
Correct answer: Liver- A. Endothelial cells
- B. Clara cells
- C. Fibroblast
- D. Mast cells
Explanation: Clara cells, now called club cells, are secretory epithelial cells of the bronchioles and arise from endoderm.
Correct answer: Clara cells- A. They are cylindrical in shape
- B. Have multiple nuclei
- C. Have transverse striations
- D. The nuclei are central
Explanation: Skeletal muscle fibres are long and cylindrical, have multiple peripheral nuclei, and show transverse striations.
Correct answer: The nuclei are central- A. Right CCA is a branch of brachiocephalic artery
- B. Left CCA is a branch of arch of aorta
- C. The CCA is divided into external and internal carotid arteries at the level of upper border of thyroid cartilage
- D. Carotid sinus acts as a chemoreceptor
Explanation: The carotid sinus is a baroreceptor that detects blood-pressure changes, whereas the nearby carotid body is the chemoreceptor.
Correct answer: Carotid sinus acts as a chemoreceptor- A. 6th
- B. 7th
- C. 4th
- D. 9th
Explanation: The facial nerve exits the skull at the stylomastoid foramen and crosses the region near the angle of the mandible, making it vulnerable…
Correct answer: 7th- A. Trigeminal nerve
- B. Facial nerve
- C. Occulomotor nerve
- D. Glossopharyngeal nerveExplore Anatomy Models
Explanation: General sensation from the nasal cavity is carried mainly by branches of the trigeminal nerve, especially the ophthalmic and maxillary…
Correct answer: Trigeminal nerve- A. Ascending pharyngeal
- B. Ascending palatine
- C. Middle meningeal artery
- D. Artery of pterygoid canal
Explanation: The pharyngotympanic tube receives branches from the ascending pharyngeal, middle meningeal and artery of the pterygoid canal.
Correct answer: Ascending palatine- A. Taste
- B. Lacrimation
- C. Saliva
- D. Sweating
Explanation: The geniculate ganglion contains sensory cell bodies for taste carried by the nervus intermedius, chiefly from the anterior two-thirds of…
Correct answer: Taste- A. Greater petrosal nerve
- B. Lesser petrosal nerve
- C. Sphenopalatine nerve
- D. Nasocilliary nerveExplore Anatomy Models
Explanation: Preganglionic parasympathetic fibres for lacrimation travel in the greater petrosal nerve to the pterygopalatine ganglion, then reach the…
Correct answer: Greater petrosal nerve- A. Cavernous branch
- B. Inferior hypophyseal
- C. Meningeal artery
- D. Ophthalmic artery
Explanation: The ophthalmic artery arises from the supraclinoid part of the internal carotid artery after it leaves the cavernous sinus.
Correct answer: Ophthalmic artery- A. Facial Nerve
- B. Chorda Tympani
- C. Mylohyoid Nerve
- D. Lingual Nerve
Explanation: Secretomotor fibres reach the submandibular gland through the facial nerve, chorda tympani and lingual nerve, with relay in the…
