What are the functions of the Glottis and Tounge in a frog and where are they located?
The Correct Answer and Explanation is :
The glottis and tongue in a frog serve important roles related to feeding, respiration, and vocalization.
Glottis:
The glottis is an opening located in the frog’s mouth, found at the back of the oral cavity. It is a slit-like opening that leads to the frog’s trachea, which connects to the lungs. The primary function of the glottis is related to respiration. When the frog is breathing, the glottis helps regulate airflow by opening and closing, allowing air to pass into the trachea and into the lungs. During vocalization, the glottis also plays a role in sound production. Frogs use their vocal cords (located near the glottis) to produce calls. The glottis can open and close rapidly to facilitate this sound production, especially when the frog is calling during mating season.
Tongue:
The tongue of a frog is located in the mouth, attached at the front of the lower jaw. Unlike humans, a frog’s tongue is attached at the front of the mouth and can be rapidly extended out to capture prey. The tongue is typically long, smooth, and sticky, which helps the frog catch insects and other small prey. The tongue is highly specialized for predation, and when the frog spots its prey, the tongue is flicked out at an incredible speed. It adheres to the prey, and the frog retracts its tongue back into its mouth, bringing the prey along with it. This rapid and efficient feeding mechanism allows frogs to capture moving prey effectively.
In summary, the glottis is involved in respiration and vocalization and is located at the back of the mouth, leading to the trachea. The tongue, on the other hand, is used for capturing prey and is located at the front of the mouth, functioning as a specialized feeding tool in frogs.
