Animal Tissue and Anatomy Questions
-
Cricoid cartilage
-
Thyroid cartilage
-
Corniculate cartilages
-
Arytenoid cartilages
-
Cuneiform cartilages
B
Correct answer
Explanation
This forms the Adam's apple. It is usually larger in males than in females. The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone.
-
Interlobular ducts
-
Intralobular ducts
-
An excretory intralobular duct
-
A striated duct
-
An intercalated duct
B
Correct answer
Explanation
Intralobular ducts join to form the interlobular duct, which is located outside the lobule, between adjacent lobules. An interlobular duct is lined by pseudostratified columnar epithelium.
-
Fallopian tubes
-
Mons pubis
-
Clitoris
-
Labia majora
-
Labia minora
C
Correct answer
Explanation
On the superior end of the labia minora is a small mass of erectile tissue known as the clitoris that contains many nerve endings for sensing sexual pleasure.
-
Radix
-
Raphe
-
Epithelium
-
Corpus spongiosum
-
Corpus cavernosum
B
Correct answer
Explanation
The raphe is the visible ridge between the lateral halves of the penis.
-
Spinal cord
-
Brain
-
Oropharynx
-
Liver
C
Correct answer
Explanation
Besides intestine, poliovirus also multiplies in the oropharynx.
-
Dermoid cyst
-
Thyroglossal tract cyst
-
Median palatal cyst
-
Globulomaxillary cyst
-
Median mandibular cyst
A
Correct answer
Explanation
Dermoid cyst occurs mostly on the face, neck or scalp.
-
pharynx
-
larynx
-
glottis
-
None of the above
B
Correct answer
Explanation
The epiglottis is a leaf-shaped cartilage flap that is part of the larynx (voice box). It closes over the trachea during swallowing to prevent food/liquid from entering the airway. The pharynx is the throat cavity, glottis is the vocal cord opening - neither contains the epiglottis.
-
pharynx
-
larynx
-
gill pouch
-
All of the above
C
Correct answer
Explanation
In embryonic development, oral structures including jaw components derive from pharyngeal arches which are formed from the gill pouch region. The pharynx itself is a cavity, larynx is lower - neither gives rise to prominent oral structures.
-
fissure completely
-
fissure incompletely
-
false septum
-
None of the above
A
Correct answer
Explanation
In humans, the liver is divided into right and left lobes by the falciform ligament, which creates a complete fissure on the anterior surface of the liver. This anatomical separation is complete and distinct, unlike incomplete septa or partial divisions found in some other species.
-
liver
-
stomach
-
ileum
-
kidney
D
Correct answer
Explanation
The caudate lobe of the liver is located posteriorly and is in close proximity to the kidney, particularly the right kidney. The post caval vein (inferior vena cava) passes through this region. The liver itself, stomach, and ileum are not the closest structures to this part of the caudate lobe.
-
buccal cavity
-
roof of nasal cavities
-
floor of nasal cavities
-
optocoel of brain
C
Correct answer
Explanation
Jacobson's organ (vomeronasal organ) is located in the floor of the nasal cavities in many vertebrates. It's an accessory olfactory organ that detects pheromones and other chemical signals. It is not found in the buccal cavity, roof of nasal cavities, or optocoel of the brain.
-
caudate lobe
-
right lobe
-
left lobe
-
quadate lobe
B
Correct answer
Explanation
In mammals, the gall bladder is attached to the right lobe of the liver. The gall bladder stores and concentrates bile, which is produced by the liver and released into the digestive system. It is not attached to the caudate lobe, left lobe, or quadrate lobe.
-
Lungs
-
Liver
-
Kidney
-
All of these
B
Correct answer
Explanation
The liver is the primary organ affected by alcohol consumption because it metabolizes alcohol. Chronic alcohol consumption can lead to fatty liver, alcoholic hepatitis, and cirrhosis. While alcohol affects multiple organs, the liver bears the primary impact.
-
mouth
-
intestine
-
respiratory tract
-
kidney tubules
-
ducts of salivary glands
C
Correct answer
Explanation
This is where absorption and secretion occurs, as in the inner lining of the intestines, tallciliated columnar epithelium cells are present.
-
chest wall and breast
-
bladder
-
pelvis
-
inner ear
-
Both (1) and (2)
C
Correct answer
Explanation
The internal iliac artery supplies to the walls and viscera of the pelvis, the buttock, the reproductive organs and the medial compartment of the thigh.
