Study Notes

Skin and Its Structure

  • The superficial part of the skin is called the epidermis.
  • The skin's appendages include hair follicles, sebaceous glands, sweat glands, and nails.
  • The part of the skin that contains numerous blood vessels, lymphatic vessels, and nerves is the dermis.
  • Subcutaneous tissue (or hypodermis) unites the dermis to the underlying deep fascia.

Muscle Types

  • Skeletal muscle is often referred to as voluntary muscle because it is controlled consciously.
  • The three types of muscle include skeletal muscle, smooth muscle, and cardiac muscle.
  • Skeletal muscles produce movements by contracting in response to nervous system signals.

Specialized Skin Areas

  • The skin on the palms of the hands and soles of the feet is notably thick due to the presence of a thick epidermis, providing resistance to abrasion.
