Question
Why is the dorsal side of the frog more pigmented than the ventral side?
Answer
To provide camouflage and protection from predators.
2
Question
What structures form the external parts of the frog's body?
Answer
Snout, mouth, eyes, nostrils, tympanic membrane, browspot, hump, anus, forelimbs, hindlimbs.
3
Question
What structures are involved in the frog's mouth cavity?
Answer
Maxillary teeth, upper lip, sulcus marginalis, median subrosal fossa, pulvinars, choanae, vomerine teeth, Eustachian tube openings, tongue, tuberculum prelinguale, prelingual fossa, pharynx, laryngeal prominence, glottis, esophagus opening, vocal sac openings.
4
Question
What is the main role of the structures in the frog's buccal cavity?
Answer
Facilitate prey capture, mouth opening, and initial digestion.
5
Question
What is the purpose of grooves, ridges, depressions, and tubercles in the frog’s mouth cavity?
Answer
Hold, guide, and prevent prey escape, directing food toward the throat.
6
Question
What is the mammalian equivalent of the frog's transverse septum?
Answer
The diaphragm, which divides the thoracic and abdominal cavities.
7
Question
How does the body cavity structure of humans compare to that of frogs?
Answer
Humans have a divided cavity with the diaphragm, enabling organ specialization; frogs have a single undivided cavity.
8
Question
What is the function of the Eustachian tube openings in frogs?
Answer
Connect the buccal cavity to the middle ear for pressure regulation.
9
Question
What is the role of the glottis in frogs?
Answer
Connects the mouth cavity to the larynx for air passage during respiration.
10
Question
Why are the internal nares (choanae) important in frogs?
Answer
Allow passage of air from the nostrils to the pharynx.
11
Question
What structure suspends the internal organs within the frog's coelom?
Answer
The mesentery.
12
Question
What is the purpose of the transverse septum in the frog?
Answer
Partition separates the coelom into two compartments.
13
Question
Describe the function of the pericardial cavity in frogs.
Answer
Contains the heart, facilitating circulation.
14
Question
What is the role of the pleuro-peritoneal cavity in frogs?
Answer
Houses lungs, stomach, kidneys, gonads, and other visceral organs.
15
Question
Why is the dorsal side of a frog more pigmented?
Answer
For camouflage and predator protection in the natural environment.
16
Question
How can gender be distinguished in a frog?
Answer
Male frogs have pigment spots on the ventral jaw angles.
17
Question
What external structures comprise a frog's body?
Answer
Snout, eyes, nostrils, tympanic membrane, limbs, and associated features.
18
Question
What is the function of the frog's tympanic membrane?
Answer
Detects sound vibrations for auditory perception.
19
Question
What roles do mouth cavity structures serve in frogs?
Answer
Assist in prey capture, mouth opening, and initial digestion.
20
Question
How does the frog's body cavity compare to humans?
Answer
Frog cavity is undivided; humans have a divided cavity with diaphragm.
21
Question
What is the function of oral grooves, ridges, and tubercles?
Answer
Guide prey into the throat and prevent escape.
22
Question
How is the human mouth cavity more advanced than a frog's?
Answer
Humans have complex teeth, tongue, taste buds, salivary glands, and palate for better function.
23
Question
What is the mammalian equivalent of the frog's transverse septum?
Answer
The diaphragm, separating thoracic and abdominal cavities.
24
Question
How does human body cavity structure differ from that of frogs?
Answer
Humans have a divided, diaphragm-supported cavity; frogs have a single undivided one.
25
Question
What is the function of Eustachian tubes in frogs?
Answer
Connect the mouth to the middle ear to regulate pressure.
26
Question
What does the glottis do in frogs?
Answer
Links the mouth cavity to the larynx, enabling respiration.
27
Question
Why are choanae important in frogs?
Answer
Allow air passage from nostrils to the pharynx.
28
Question
What is the significance of lymph sacs?
Answer
Store lymph, aid in immune response.
29
Question
Which structure suspends internal organs in frogs?
Answer
The mesentery.
30
Question
How does the frog's body cavity design aid organ function?
Answer
Flexible space with membranes and septa allows organ movement and organization.
