b. contains the final bifurcation of the external carotid artery within its 
    glandular tissue

c. open into the oral cavity via a duct at the level of the first upper 
    molar tooth

d. contains the facial nerve which divides into five branches within its 
    glandular tissue

e. is a mainly serous salivary gland


2. The submandibular gland:

b. overlies the hyoglossal nerve

c. is a mainly serous salivary gland

d. develops as a tubular endodermal outgrowth from the floor of the

3. The thyroid gland:
