Multiple choice
  1. Cricoid cartilage

  2. Thyroid cartilage

  3. Corniculate cartilages

  4. Arytenoid cartilages

  5. 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.

Multiple choice
  1. pharynx

  2. larynx

  3. glottis

  4. 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.

Multiple choice
  1. pharynx

  2. larynx

  3. gill pouch

  4. 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.

Multiple choice
  1. fissure completely

  2. fissure incompletely

  3. false septum

  4. 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.

Multiple choice
  1. liver

  2. stomach

  3. ileum

  4. kidney

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. buccal cavity

  2. roof of nasal cavities

  3. floor of nasal cavities

  4. optocoel of brain

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. caudate lobe

  2. right lobe

  3. left lobe

  4. quadate lobe

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Lungs

  2. Liver

  3. Kidney

  4. 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.

Multiple choice
  1. mouth

  2. intestine

  3. respiratory tract

  4. kidney tubules

  5. 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.

Multiple choice
  1. chest wall and breast

  2. bladder

  3. pelvis

  4. inner ear

  5. Both (1) and (2)
