    Three layers of muscle causes the muscularis externa to be seem large when compared with the rest of the GI tract
  • Inner Oblique
  • A: Inner oblique

    B: Middle circular
  • A: Middle circular

    B: Outer longitudinal

    C: Fibroserosa
Intestinal Smooth Muscle
  • A: Muscularis externa has 2 layers which are the same in the small and large intestine

    B: Submucosa is loose connective tissue

    C: Mucosa
  • A: Outer longitudinal muscle layer

    B: Auerbach's plexus is located between the outer and inner muscle layers

    C: Inner circular muscle layer

    D: Submucosa is loose connective tissue

    E: Muscularis mucosa is a thin smooth muscle layer located just beneath the mucosa
  • A: Inner circular muscle layer

    B: Auerbach's plexus
  • A: Inner circular

    B: Auerbach's plexus

    C: Outer longitudinal

    D: Fibroserosa
Uterus Smooth Muscle
  • A: Endometrium

    B: Uterine glands are simple multicellular branched tubular glands

    C: Myometrium is smooth muscle irregualrly arranged and is important in child birth
