Integumentary System

The integumentary system plays a crucial role in human health, featuring components such as sebaceous and sweat glands, nails, and various epithelial tissues. It secretes oil to moisturize skin and inhibit bacterial growth while regulating body temperature through sweat. The dermis, rich in connective tissues like collagen, provides skin support. Common conditions include acne, hyperhidrosis, and albinism. This overview provides insights into the structure and functions of the integumentary system, helping to understand its importance in overall well-being.

  20. Is in the dermis: __________ is released in an injury: anticoagulant (Mast cell)

  21. Heparin

  22. Is in the dermis: __________ is released in response to an anllergy (Mast cell)

  23. Histamine

  24. Locatedjust below the skin, connects the skin to the muscles.

  25. Subcutaneous Layer

  26. The “fat” layer

  27. Adipose tissue

  28. Deposits of dimpled fat – still just fat

  29. Cellulite

  30. Nails

  31. Acute or chronic infection of the skin fold around the nailk

  32. Paronychia

  33. Pathology of the Integumentary System Commonly known as acne caused by an over production of sebum

  34. Acne Vulgaris
