Study Notes

Integument and its Derivatives in Vertebrates

Comparative anatomy studies animal structures, focusing on how different groups are similar or different, and their evolutionary origins.
Integument, or skin, is the outermost protective layer of an animal's body. It includes conjunctiva, external eardrums, and mucous membranes of the mouth, rectum, nostrils, eyelids, and the urinogenital ducts.
Integument has several functions, including protection from the environment
Protection: The integument separates an animal from its external environment, shielding it from injury, chemicals, and disease. Specialized structures like scales, feathers, and hairs also reduce injury and keep moisture in.
Locomotion: Skin structures like dermal fin rays in fish, and webbed feet in amphibians aid in movement in water. Adaptations like claws and feathers support climbing or flying.
Secretion: Skin glands produce various substances—mucous for keeping skin moist, poisons to deter predators, oils to condition feathers or fur, and milk for nourishment.
Sensation: Nerve endings in the skin provide information about touch, temperature, pain, and pressure. This sensory input is crucial for survival.
Sexual Selection: Bright colors or other elaborate structures attract mates. This can include antlers, plumage, or skin coloration.
Temperature Regulation: Integumentary blood vessels dilate to release heat or constrict to retain heat. Feathers and fur provide insulation.
Excretion: Skin plays a role in eliminating waste products, especially in water-based animals. Sweat in mammals is an example of this.
Food Storage: Blubber and subcutaneous fat act as insulation and a stored food source.

Epidermal Derivatives

Epidermal structures are derived from the epidermis (outer layer) of skin.
Exoskeletons such as scales, beaks, claws, nails, hooves, feathers, and hairs originate from the epidermis and protect the body of the animal.
Various glands, like mucous, poison, uropygial, sweat, sebaceous, scent, and mammary glands, are also epidermal derivatives.

Dermal Derivatives

Dermal derivatives originate in the dermis (inner layer) of skin.
Examples include bony scales (e.g., in fishes, crocodiles), dermal plates or scutes (terrestrial vertebrates) including fin rays in fishes forming the endoskeleton.

Types Of Scales

Cosmoid scales: From extinct lobe-finned fishes
Placoid scales: Sharks and rays
Ganoid scales: From ganoid fishes
Cycloid scales: From teleost fishes
Ctenoid scales: From teleost fishes
Dermal scales: Found in reptiles and some amphibians
