Order Gymnophiona

Order of caecilians; characterized by a limbless, wormlike body, and small scales in some species.

Order Urodela

Order of salamanders; characterized by a body with head, trunk, and long tail, usually with two pairs of equal-sized limbs.

Order Anura

Order of frogs and toads; adults are characterized by a head and trunk fused, absent tail, elongated hindlimbs, and a large mouth.

Suprascapula

A bone in some vertebrates that supports the shoulder girdle, often serving as an attachment for muscles, particularly in certain amphibians and reptiles.

Scapula

A major bone in the shoulder region of vertebrates that articulates with the humerus and supports the upper limb.

Humerus

The bone of the upper front limb in frogs, connecting the shoulder and the elbow.

Radioulna

The fused bone in some vertebrates' forelimbs that combines the radius and ulna, playing a crucial role in forelimb movement and stability.

Vertebrae

The series of bones that make up the spine in vertebrates, providing structural support and protecting the spinal cord.

Ilium

The uppermost and largest bone of the pelvis, important for supporting the body and providing attachment for muscles.

Urostyle

A fused skeletal element found in the vertebral column of some amphibians, particularly frogs, which aids in locomotion and body stability.

Femur (frog)

Thigh bonein frogs that supports weight and locomotion, connecting the hip to the knee.

Tibiofibula

The bone in frogs that is a fusion of the tibia and fibula, supporting the lower limb and playing a key role in locomotion.

Cloacal opening

The posterior opening in amphibians, including frogs, through which excretion occurs and reproductive fluids are expelled.

Heart

Pumps blood throughout the body via blood vessels.

Lungs

Primary organs of respiration.

Liver

Detoxifies compounds from digested food; produces bile.

Gallbladder

Stores bile produced in the liver.

Pancreas

Produces digestive compounds & secrete them into the small intestine.

Spleen

Stores blood, recycles worn-out red blood cells, and makes white blood cells.

Stomach

Stores swallowed food and initiates digestion.

Small intestine

Completes food digestion and absorbs nutrients.

Large intestine

Absorbs water, ions, and some vitamins from digestive waste.

Fat bodies

Stores lipids (fats) for use when food is scarce.

Kidneys

Filters nitrogenous waste out of the blood.

Cloaca

Common chamber for collection of urine, feces, and sperm or eggs.

Ovaries

In females, produces eggs for reproduction.

Oviducts

In females, transports eggs from ovaries and secrete protective coating.

Testes

In males, produces sperm for reproduction.
