Study Notes
Functions of Hair and Fur
- Functions of hair/fur: insulation, moisture retention, protection, and camouflage.
- Non-primary functions include acting as sensory structures and aiding in communication.
Anatomical Terms
- Top of the nose in dogs, cats, pigs, sheep, and goats is referred to as the planum nasale.
- Claws and hooves primarily serve for traction, defense, and manipulation, but not primarily for flight or other non-supportive activities.
Glands and Secretions
- Sebaceous glands produce a secretion that coats hair, trapping moisture.
- Apocrine sweat glands are not present in planum nasale or footpads.
- Anal glands store secretions expressed during defecation or when an animal is frightened or excited.
Hair Growth Phases
- The telogen phase is the resting phase of hair growth when hair stops growing.
- The anagen phase is the active growth phase when the hair shaft lengthens.
- The transitional phase between anagen and telogen is known as the catagen phase.
Skin Anatomy and Function
- The epidermis primarily consists of keratinocytes.
- The stratum corneum is the outermost and thickest layer of the epidermis.
- Keratinization occurs in the stratum granulosum.
- The dermis provides structure and nourishment to the skin.
- Dermal papillae are formed in the papillary layer just beneath the epidermis.
Specialized Cells and Structures
- Langerhans cells function in immune response within the epidermis.
- Merkel cells are involved in the sensation of touch and pressure.
- Melanocytes produce melanin, contributing to skin pigmentation.
Foot and Paw Pads
- Foot/paw pads are primarily composed of adipose tissue for thermoregulation and shock absorption.
- Ergots and chestnuts are vestigial structures located on the limbs of some animals.
- Function of foot/paw pads includes providing traction and protection against abrasive surfaces.
Other Notable Structures
- Antlers are characterized as seasonal bony structures that are shed annually, unlike permanent horns, which are present throughout life.
- Hypodermis functions in insulation, storage, and attachment of skin to underlying tissues.
- The cutaneous pouches of sheep include specialized skin structures used for communication and thermal regulation.
Additional Notes
- The loss of a large percentage of hair volume due to metabolic stress or illness is termed telogen effluvium.
- The cornified layer facilitates barrier functions as it retains moisture and protects against environmental damage.
- Giraffes and okapis possess horn-like structures, with distinct characteristics in gender pertaining to okapis.
