Anatomy MCQs Set 1
1. Bones are bound together with the help of strong bands called as
a. Tendon b. Ligament c. Aponeurosis d. None of above
Correct Answer: (b) Ligament
A ligament is a strong band of dense regular connective tissue that connects bone to bone, primarily serving to stabilize joints.
2. Diarthrosis is a
a. Highly moveable joint b. Immoveable joint c. Fixed joint d. Semi moveable joint
Correct Answer: (a) Highly moveable joint
A diarthrosis (also known as a synovial joint) is characterized by a fluid-filled cavity and permits a wide range of motion, making it a highly moveable joint.
3. Gomphosis means
a. Inflammation of gums b. Implantation of teeth c. Removal of teeth from gum d. None of above
Correct Answer: (b) Implantation of teeth
A gomphosis is a type of fibrous joint where a conical process (the tooth root) fits into a socket (the alveolar process of the jaw). It is the articulation involving the implantation of teeth in the alveoli.
4. In mandible the coronoid process is turned caudally
a. In ox b. In dog c. In horse d. In pig
Correct Answer: (c) In horse
The coronoid process of the mandible is often described as being turned caudally (hooked backward) in the horse, which helps accommodate the large temporalis muscle.
5. In ribs the tubercle is concave in
a. Horse b. Ox c. Dog d. Pig
Correct Answer: (a) Horse
The articular surface of the rib’s tubercle (which articulates with the transverse process of the vertebra) is typically concave in the horse.
6. Tuber calcanei is grooved in
a. Horse b. Ox c. Dog d. Pig
Correct Answer: (b) Ox
The tuber calcanei (the heel bone projection) often exhibits a distinct groove in the ox (ruminants) for the passage of the common calcanean tendon components.
7. Fossa ovalis is a remnant of
a. Umbilical artery b. Umbilical vein c. Foramen ovale d. Coronary sinus
Correct Answer: (c) Foramen ovale
The fossa ovalis is a shallow depression in the interatrial septum, representing the closed site of the foramen ovale, which allowed blood to bypass the lungs in the fetal circulation.
8. Internal lining of the heart is called as
a. Pericardium b. Myocardium c. Endocardium d. Epicardium
Correct Answer: (c) Endocardium
The endocardium is the delicate, smooth membrane that forms the internal lining of the heart chambers and covers the heart valves.
9. The largest cranial nerve is
a. Trochlear b. Trigeminal c. Oculomotor d. Facial
Correct Answer: (b) Trigeminal
The trigeminal nerve (CN V) is the largest cranial nerve in terms of the diameter of its sensory root and its extensive distribution.
10. Tuber ischii is three sided in
a. Horse b. Ox c. Dog d. Goat
Correct Answer: (b) Ox
The tuber ischii (the caudal prominence of the ischium) in the ox (bovine) is characteristically large and distinct, often described as having three surfaces or sides.
11. Ischial arch is narrow and deep in
a. Horse b. Ox c. Dog d. Goat
Correct Answer: (b) Ox
The ischial arch (the space between the ischiatic tuberosities) is typically described as being narrow and deep in the ox compared to the horse.
12. membrane on the surface of the bone is called as
a. Endosteum b. Periosteum c. Perichondrium d. None of above
Correct Answer: (b) Periosteum
The periosteum is a dense fibrous membrane that covers the outer surface of bone (except at joints).
13. The ligament present between two horns of uterus is
a. Broad ligament b. Proper ligament c. Intercornual ligament d. Suspensory ligament
Correct Answer: (c) Intercornual ligament
The intercornual ligament is a fibrous connection that joins the apex of the two uterine horns, particularly prominent in ruminants.
14. Inguinal canal has following number of openings
a. One b. Two c. Three d. Four
Correct Answer: (b) Two
The inguinal canal has two openings: the deep inguinal ring (internal) and the superficial inguinal ring (external).
15. Urethra has
a. Pelvic part b. Extrapelvic part c. Both a & b d. None of above
Correct Answer: (c) Both a & b
The urethra in males (and to some extent in females) is divided into the pelvic part (within the pelvic cavity) and the extrapelvic part (e.g., the penile part in males).
16. Horns are the extensions of the
a. Temporal bone b. Parietal bone c. Frontal bone d. None of above
Correct Answer: (c) Frontal bone
The osseous core of horns is formed by an extension of the frontal bone, called the corneal process.
17. In ox deltoideus muscle has
a. Two parts b. Three parts c. Four parts d. None of above
Correct Answer: (a) Two parts
The deltoideus muscle is typically described as having two distinct parts in the ox (bovine): the scapular part and the acromial part.
18. Cytology is the study of
a. Cells b. Different sites c. Study under electron microscope d. Tissues
Correct Answer: (a) Cells
Cytology is the branch of biology focused on the structure, function, and pathology of cells.
19. Topographic anatomy is the study of
a. Relative position of different organs b. Superficial study of structure c. Deep study of structure d. None of above
Correct Answer: (a) Relative position of different organs
Topographic anatomy (or regional anatomy) focuses on the relative position and spatial arrangement of organs and structures within a specific region of the body.
20. Leg contains
a. Radius and Ulna b. Tibia and Fibula c. Metacarpal d. Metatarsal
Correct Answer: (b) Tibia and Fibula
In standard anatomical terminology, the “leg” refers to the distal portion of the hindlimb, which contains the tibia and fibula.
21. CSF can be collected from
a. Dura mater b. Pia mater c. Subarachnoid space
Correct Answer: (c) Subarachnoid space
Cerebrospinal fluid (CSF) circulates and is contained within the subarachnoid space (the space between the arachnoid mater and the pia mater) and is typically collected from this space.
22. Trochlea, a pulley like structure, is present in
a. Scapula b. Femur c. Humerus
Correct Answer: (c) Humerus
The trochlea (from the Greek for “pulley”) is the spool-shaped articular surface on the distal end of the humerus that articulates with the ulna to form the elbow joint.
23. In mare broad ligament has attachment with
a. Lateral abdominal wall b. Sub lumbar region c. With caudal wall
Correct Answer: (b) Sub lumbar region
The broad ligament in the mare (female horse) attaches the uterus and ovaries to the walls of the pelvic and abdominal cavities, with a significant attachment point dorsally in the sublumbar region.
24. There are tarsal bones in horse
a. Six b. Seven c. Eight
Correct Answer: (a) Six
Due to the fusion of certain elements, the horse typically possesses six tarsal bones in the hock.
25. Distal articular surface is oblique in tibia of
a. Horse b. Ox c. Dog
Correct Answer: (b) Ox
The distal articular surface of the tibia that articulates with the tarsus is distinctively oblique in the ox (ruminants), contributing to the arrangement of the hock joint.
