Study Notes
Frog Species and Anatomy
- Ranna vittegera refers to the Field Frog.
- Ranna catesbeina is known as the Bullfrog.
- Frogs have an anatomy divided into two major parts: the axial region, which includes the head and trunk, and the appendicular region, consisting of the limbs.
External Structures
- The snout is a triangular protruding region on the frog's head.
- Eyes are located on the sides of the head and consist of upper and lower eyelids, along with a nictitating membrane, which functions as a third eyelid.
- Nostrils, also called external nares, are small openings near the tip of the snout.
- The tympanic membrane, a thickened membrane behind each eye, plays a crucial role in hearing.
- A brow spot is a lightly colored area in front of the eyes at the median dorsal part of the head.
- The hump is an elevation located on the mid-dorsal trunk near the posterior end.
- The anus is found at the dorsal end of the trunk, serving for the exit of reproductive cells, waste, and undigested matter.
Limb Anatomy
- The frog's forelimbs, located at the anterior end of the trunk, consist of the upper arm, forearm, wrist, and manus (hand) which has four digits.
- The hindlimbs at the posterior end consist of the thigh, shank, ankles, and feature webbed toes.
- The prehallux is a sixth toe located on the inner side of the foot, near the most proximal toe, while the hallux is the most proximal toe.
Skeletal System
- The skeleton is a vital component of all vertebrates, providing structural support and protection for softer body parts.
- Three primary functions of the skeleton:
- Acts as a framework or support.
- Provides a surface for muscle attachment, aiding in movement and locomotion.
- Supplies calcium to blood cells.
- The vertebrate endoskeleton is divided into two main categories: axial skeleton (includes skull, vertebral column, and ribs—absent in frogs) and appendicular skeleton (comprising the limbs and limb girdles).
Classification of Frogs
- Frogs belong to the phylum Chordata and the subphylum Vertebrata.
- They are classified under the class Amphibia.
- The order of frogs is known as Anura, and they belong to the family Ranidae, with Rana as their genus.
