Mandibular Salivary Gland

Mandibular Salivary Gland - Copyright Nottingham 2008
  • Merocrine secretion
  • Generally smaller than the parotid gland
  • It is a moderately large gland in carnivores
  • It is a large gland in herbivores
  • Compact
  • Located around angle of jaw
  • Mandibular duct runs ventral to mucous membrane of floor of oral cavity, close to frenulum of tongue
  • Duct opens at sublingual caruncle
  • Innervated by facial nerve (CN VII) via chordi tympanii of trigeminal (CN V)
