  1. Actin - thin contractile myofilament; anchored at the Z discs
  2. Myosin - thick contractile myofilament; anchored at the M line in the middle of the sarcomere.
  3. Troponin - regulatory protein of the sarcomere; attached to the thin filament 
  4. Tropomyosin - regulatory protein of the sarcomere; attached to the thin filament
  5. Z Line - also known as z-disc; forms the borders of the sarcomere; anchors myofilaments 
  6. M Line - runs down the center of the sarcomere, through the middle of the myosin filaments
  7. A Band - at the center of the sarcomere; myosin and actin filaments overlap in peripheral regions of the A band, whereas a middle region (called the H zone) contains only myosin
  8. I Band - the region of the sarcomere with thin filaments only 
  9. H Zone - the region of the A-band; has thick filaments only 



  1. Stratum Basale - the deepest epidermal layer, one-layer of cuboidal cells
  2. Stratum Spinosum - superficial to stratum basale, 8 -10 layers of keratinocytes, looks “spiny”
  3. Stratum Granulosum - superficial to stratum spinosum, has a grainy appearance, 3-4 layers
  4. Stratum Lucidum - seemingly translucent layer; only found in thick skin between strata granulosum and corneum
  5. Stratum Corneum - most superficial layer, 30-40 layers of dead cells
  6. Epidermis - superficial layer of the skin; made of epithelial tissue
  7. Dermis - deeper layer of the skin; made of connective tissue
  8. Hypodermis - layer directly inferior to the dermis, has blood vessels and adipose tissue
  9. Dermal Papilla - a finger-like projection, or fold, of the dermis into the epidermis; increases the strength of the connection between the epidermis and dermis
  10. Arrector Pili Muscle - a smooth muscle connected to each hair root; contracts to make the external hair shaft “stand up.” 
  11. Reticular Layer - thicker layer of dermis, inferior to the papillary layer; well vascularized and has a rich nerve supply; appears reticulated (net-like) due to a tight meshwork of fibers.
  12. Sebaceous (Oil) Gland - in mid-dermis; have a duct emptying into the hair follicles; found all over the body;  helps to lubricate and waterproof the skin and hair
  13. Pacinian Corpuscle - touch receptor in reticular layer of dermis; looks lamellated (bulbous)
  14. Meissner’s Corpuscle - touch receptor in the papillary layer of the dermis; located in dermal papilla
  15. Sweat Gland (eccrine type) - coiled gland lying deep in the dermis, with the duct rising up to a pore on the skin surface, where the sweat is released.
  16. Hair Follicle - tunnel looking structure in the skin; houses the hair root
