Study Notes

Frog Anatomy and Physiology

  • Webbed digits on the feet of frogs aid in swimming and buoyancy.

Sex Identification

  • Males can be distinguished from females by their smaller size, vocal cords, and presence of a vocal sac.

Organ Systems

  • The nervous system in frogs has a well-developed structure and function.

Brain Structure

  • The midbrain is characterized by a pair of optic lobes.

Reproductive Organs

  • The male reproductive organs in a frog are called testes.

Sensory Organs

  • The otic capsule is responsible for hearing as well as balancing (equilibrium).

Skull Anatomy

  • The eyes are situated on the top of a frog's skull.

Adaptation to Environment

  • Summer sleep (aestivation) and winter sleep (hibernation) help frogs conserve energy during periods of food scarcity and extreme temperatures.

Camouflage

  • Frogs have the ability to change color to blend in with their environment for camouflage and protection.

Skin Secretions

  • Mucus on the skin of a frog helps to prevent water loss, protects against dehydration, and aids in skin lubrication.

Test your knowledge about the external features and anatomy of frogs. Learn about the hind limbs, fore limbs, webbed digits, sexual dimorphism, and organ systems in the body cavity of frogs.
