Integumentary System Quiz physio

Hair/Fur Functions

• Insulation, protection, sensory input, and camouflage are primary functions of hair/fur.
• Not providing oxygen transfer is a function hair/fur does not perform.

Sebum Production

• Sebaceous glands are responsible for producing sebum, which helps in lubricating the skin and fur.

Sweat Gland Locations

• Sweat glands are typically found in areas such as paw pads and between toes in most domestic species.

Tail Glands

• Tail glands in dogs and cats function in communication through scent marking and signaling social status.

Claws and Hooves Characteristics

• Claws and hooves do not possess the same structure and function as nails found in other species.

Horns vs. Antlers

• The primary difference is that horns are permanent and typically unbranched, while antlers are bony, branched, and shed annually.

Anal Sacs Function

• Anal sacs function to produce a strong scent used for marking territory and communication.

Hair Growth Cycle

• The resting phase of the hair growth cycle is known as the telogen phase.

Composition of Sebum

• Sebum is composed primarily of lipids, including triglycerides, fatty acids, wax esters, and squalene.

Cutaneous Pouches in Sheep

• The function of cutaneous pouches in sheep includes secretion of oils that may help in protection and communication.

Epidermis Composition

• The outermost layer of the skin, mainly comprising dead cells, is the stratum corneum.

Keratinization Function

• Keratinization is essential for forming a protective barrier against environmental damage and water loss.

Melanin Production

• Melanocytes are the cells responsible for producing melanin, contributing to the color of skin, fur, and eyes.

Keratinization Layer

• The stratum granulosum layer of the epidermis is responsible for keratinization.

Skin's Structural Strength

• The dermis, particularly the reticular layer, is the largest part of the skin that provides structural strength.

Dermis Layers

• The papillary layer is the layer of the dermis just beneath the epidermis.

Reticular Layer Tissue Type

• The reticular layer of the dermis is composed of dense irregular connective tissue.

Integument Special Feature

• A special feature of the integument that comprises all five epidermal layers is the hoof.

Nose Top in Animals

• The top of the nose is referred to as the "planum" in dogs, cats, pigs, sheep, and goats.

Dark Brown Horny Patches

• The dark brown, horny patches on the legs of horses and other equids are known as "chestnuts."
