Function of special visceral efferent of facial nerve?
CN VII
Branchial motor - stapedius, stylohyoid, posterior belly of digastric muscles, facial expression, buccinator, platysma, occipitalis muscles
General visceral efferent function of facial nerve
CN VII
Lacrimal, submandibular, and sublingual glands. Mucous membrane of nose and hard/soft palates
General somatic Afferent function of facial nerve
CN VII

In terms of biomechanics, define effort, load, and fulcrum
Effort - part that performs the work/work is required
Load - part being moved/resistance arm
Fulcrum - point of movement = joint
