Examples of lacrimal gland in the following topics:
-
- 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).
-
- Simultaneously, the adrenal gland also releases catecholamine hormones, such as adrenaline or noradrenaline, into the blood stream.
- Inhibition of the lacrimal gland (responsible for tear production) and salivation.

-
- The parasympathetic nervous system regulates organ and gland functions during rest and is considered a slowly activated, dampening system.
- The ANS is responsible for regulating the internal organs and glands, which occurs unconsciously.
- 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).
-
- 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.
-
- In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
- In mammals, the adrenal glands (also known as the suprarenal glands) are endocrine glands that sit atop the kidneys.
- In humans, the right adrenal gland is triangular shaped, while the left adrenal gland is semilunar shaped.
- Each adrenal gland has two distinct structures, the outer adrenal cortex and the inner medulla—both produce hormones.
- The adrenal glands are triangular-shaped organs on top of the kidneys.
-
- Sweat glands, also known as sudoriferous glands, are distributed over most of the body surface.
- Sweat glands, also called
sudoriferous glands, are simple tubular glands found almost everywhere on our
body.
- The other kind of sweat glands are known as apocrine
glands.
- Unlike eccrine glands, the exact function of apocrine glands is unknown and
debated.

-
- The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone.
- The parathyroid glands are small endocrine glands—approximately the size of a grain of rice—in the neck that produce parathyroid hormone.
- Humans usually have four parathyroid glands, which are usually located on the posterior surface of the thyroid gland, or, in rare cases, within the thyroid gland itself or in the chest.
- The two parathyroid glands on each side that are positioned higher are called the superior parathyroid glands, while the lower two are called the inferior parathyroid glands.
- The parathyroid gland in relation to the thyroid gland.
-
-
- Sebaceous glands are found in the skin all over the body (except the palms of the hands and the soles of the feet).
- The sebaceous glands are microscopic glands found in the skin of mammals .
- In the eyelids, meibomian sebaceous glands secrete a special type of sebum into tears.
- In the glands, sebum is produced within specialized cells and is released as these cells burst; sebaceous glands are thus classified as holocrine glands.
