a. Eccrine:
- throughout body
- simple tubular glands
- control body T by evaporation (remember your physics!)
- Innervated by Sympathetic fibres of autonomic nervous system.
b. Apocrine:
- Large glands
- Found in AAM i.e. 1. Axilla 2. Anogenital region 3. Mammary Areola
- ducts open into hair follicle
- saline secretion more viscous than eccrine glands
- present throughout the skin except PS i.e. Palms and soles
- produce sebum which is protective covering for skin.
sebaceous = σπυρούδκια. 'Εφκαλα ποττε σπυρκα πας τα palms and soles? όι!

Εξέρετε ότι η εμβρυογένεση είναι πολλά πολλά υπερβολικά παρόμοια σε ούλλα τα θηλαστικά? (Τζαι αρκετά παρόμοια στα αρχικά στάδια με άλλα ζώα?).
Εξέρετε ότι πίσω που το θυροειδή έσιει αλλο 4 παραθυροειδικούς αδένες που εν υπεύθυνοι για το regulation του ασβέστιου? I didn't!

Emissary veins
One important emissary vein communicates from outside the skull through the sphenoidal emissary foramen inferior to the zygomatic archwith the cavernous sinus on the inside of the skull. This is an important route for spread of infection because cranial nerves III, IV, V1, V2, and VI and the internal carotid pass through the cavernous sinus. Subsequent infection or inflammation in the cavernous sinus can result in damage to any of the cranial nerves that pass through it or meningitis. Also, rupturing the emissary veins will result in a subdural hematoma which will compress the brain.The emissary veins are valveless veins which normally drain external veins of the skull into the dural venous sinuses. However, because they are valveless, pus can flow into the skull through them as well, making them a possible route for transmission of extracranial infection to get into the skull.
