Determine if your frog is a Male or Female
The sex of a frog may be determined externally by examining the thumb pads on the front feet. The thumb pads of males are enlarged at the base as in the drawing on the right.
External Anatomy of the Frog’s Head
Tympanic Membrane External Nares Nictating Membrane Frontal Membrane
Internal Anatomy of the Frog’s Head
Eustachian tube opening Internal Nares Maxillary Teeth Esophagus VomerineTeeth Glottis Tongue
Functions of the body parts that make up the frog’s head
- (^) External nares or nostrils - Anterior openings for the entry or exit of air.
- (^) Esophagus - Tube that connects the mouth and the stomach in a frog.
- (^) Tympanic Membrane - The eardrum - receives sound waves
- (^) Glottis - The opening from the mouth into the respiratory system
Functions of the External Anatomy of
the Frog
- (^) Nictitating Membrane - A transparent part of a frog’s lower eyelid that moves over the eye to clean it and protect it.
- (^) Cloacal Opening - Opening of cloaca through which undigested food, urine, eggs, and sperm are passed.
Internal Anatomy
Functions of the Internal Anatomy of a
Frog:
- (^) Large Intestine - Posterior organ of the digestive system which stores undigested food.
- (^) Liver - Secretes bile and processes digested food molecules
- (^) Urinary Bladder - The organ that collects and stores urine until released.
- (^) Fat Bodies - Masses of fat in the body cavities of frogs. Needed for hibernating and mating
- (^) Spleen - Organ in the frog’s circulatory system that makes, stores, and destroys blood cells.
- (^) Cloaca - Organ through which the products of the frogs digestive and urogenital system pass when discharged from the body.
Digestive System
Liver Small Intestines
Respiratory System
Anatomy of a Frog Heart
Functions of the Frog Heart
- (^) Heart - Pumping organ of the circulatory system (has 3 chambers).
- (^) Anterior Vena Cava - Large vein that carries blood from the anterior part of the body toward the heart.
- (^) Posterior Vena Cava - Large vein that carries blood from the posterior part of the body towards the heart.
- (^) Sinus Venosus - Sac that receives blood from the vena cava
