The anatomy of a frog

(with pictures)

Head

The head is the anterior part of the frog, containing sensory organs and the brain. It includes:

• Eyes: Provide binocular vision, adapted for detecting movement and depth perception.
• Nares (nostrils): Used for breathing; can close when underwater.
• Tympanic Membrane (eardrum): Detects sound vibrations.
• Mouth: Wide, equipped with a sticky tongue for catching prey and maxillary teeth for holding prey.

Trunk

The trunk is the central part of the frog's body, housing vital organs:

• Skin: Permeable and plays a crucial role in respiration and hydration. It contains glands that secrete mucus to keep it moist.
• Internal Organs: Includes the heart, lungs, liver, stomach, intestines, kidneys, and reproductive organs, each performing essential functions for survival.

limbs

Frogs have two pairs of limbs adapted for different modes of locomotion:

• Forelimbs: Shorter and weaker, used for support and balance during rest. They have four digits.
• Hindlimbs: Longer and more muscular, designed for jumping and swimming. They have five webbed digits, which increase surface area for efficient swimming.
