Examples of lacrimation in the following topics:

  • Facial Bones

    • The viscerocranium (face) includes these bones: vomer, 2 inferior nasal conchae, 2 nasals, maxilla, mandible, palatine, 2 zygomatics, and 2 lacrimals.
    • The two lacrimal bones form the medial wall of the orbit and articulate with the frontal, ethmoid, maxilla, and inferior nasal conchae.
    • The lacrimal bones are the two smallest bones located in the face.
    • The maxilla articulates with the zygomatic, nasal, lacrimal, and palatine bones.
    • Some, like the lacrimal and nasal bones, are paired.

  • Parasympathetic Responses

    • Its roles include stimulation of rest-and-digest activities that occur when the body is at rest, including sexual arousal, salivation, lacrimation (tears), urination, digestion, and defecation.
    • A useful acronym to summarize the functions of the parasympathetic nervous system is SLUDD (salivation, lacrimation, urination, digestion, and defecation).

  • General Features and Functions of the Skull

    • The facial skeleton contains the vomer, two nasal conchae, two nasal bones, two maxilla, the mandible, two palatine bones, two zygomatic bones, and two lacrimal bones.
    • The face is made of 2 nasal, 2 lacrimal, 2 palantine, 2 inferior nasal concha, 2 zygomatic, 2 maxilla, 1 mandible, and 1 vomer.

  • Orbits

    • The lacrimal and ethmoid bones contribute to the medial wall of the orbit and also to the medial wall of the orbital canal.

  • Parasympathetic (Craniosacral) Division

    • These paired ganglia supply all parasympathetic innervation to the head and neck: ciliary ganglion (spincter pupillae, ciliary muscle), pterygopalatine ganglion (lacrimal gland, glands of nasal cavity), submandibular ganglion (submandibular and sublingual glands), and otic ganglion (parotid gland).

  • Oculomotor (III) Nerve

    • Here the nerve is placed below the trochlear nerve and the frontal and lacrimal branches of the ophthalmic nerve, while the nasociliary nerve is placed between its two rami (the superior and inferior branch of oculomotor nerve).

  • The Fight-or-Flight Response

    • Inhibition of the lacrimal gland (responsible for tear production) and salivation.

  • Bell's Palsy

    • The facial nerves control a number of functions such as blinking and closing the eyes, smiling, frowning, lacrimation, salivation, flaring nostrils, and raising eyebrows.

  • Sympathetic Responses

    • Inhibition of the lacrimal gland (responsible for tear production) and salivation.

  • Subdivisions of the Nervous System

    • Broadly, the parasympathetic system is responsible for stimulation of "rest-and-digest" activities that occur when the body is at rest, including sexual arousal, salivation, lacrimation (tears), urination, digestion, and defecation.
