Q

describe the somatic motor pathway of the autonomic neurons

A

Q

describe the autonomic motor pathway

A

from brain stem or spinal cord the preganglionic fibres sunapse on a peripheral ganglion, then the post ganglionic fibres go to the effector.

Q

describe the general course of sympathetic fibres

A

preganglionic fibres leave spinal cord in upper thoracic region, synapse in superior cervical sympathetic ganglia. postganglionic fibres hitch-hike to blood vessels to innervate the gland

17
Q

what is the origin of the pre ganglionic fibres of parotid gland

A

inferior salivary nucleus (medulla)

18
Q

what carries the preganglionic fibres of the parotid gland

A

glossopharyngeal nerve which forms the tympanic plexus, lesser petrosal nerve and then relays the otic ganglion

19
Q

what carries the post ganglionic fibres

A

auriculotemporal nerve to innervate the parotid gland

20
Q

what is the origin of the cell bodies in sympathetic parotid gland

A

lateral horn of the spinal cord travels up the sympathetic trunk and synapses in the superior cervical ganglion.

21
Q

describe the pathway of the post ganglionic fibres for sympathatic to parotid

A

form plexus around external carotid artery

22
Q

describe the preganglionic pathway for parasympathetic innervation to submand and subling

A

originate in the superior salivatory nucleus, carried by facial nerve through chorda tympani branch that joins the lingual nerve then synapses in the submandibular region

23
Q

describe the post ganglionic parasympathetic fibres for submandibular gland

A

unnamed branches

24
Q

describe the post ganglionic parasympathetic fibres for the sublingual gland

A

joins the lingual to innervate sublingual

25
Q

describe the pre-ganglionic fibres of sympathetic ns for submand and subling

A

lateral horn of spinal cord ascend to synapse in superior cervical ganglion

26
Q

describe the post ganglionic fibres for sympathetic to submand and subling

A

derived from plexus around facial artery

27
Q

what is saliva made of

A

watery secretion, mucous, amylase and antibacterial enzyme lysozome

28
Q

what are the structural units of salivary glands

A

branched tubuloacinar

29
Q

what are the functions of salivary glands

A

serous, mucous, or mixed

30
Q

what are the smallest ducts called

A

intercalated ducts
Lined by simple cuboidal epithelium

31
Q

what are the large ducts called

A

striated ducts
Vary in epithelial lining

32
Q

parotid glands contain the smallest ducts -

A

intercalated in the intralobular regions

33
Q

parotid gland contains the biggest ducts -

A

striated in the interlobular septa

34
Q

serous acini show what kind of staining?

A

bipolar

35
Q

the apical area of serous acini are

A

zygomen granules (pink)

36
Q

the basal area of serous acini are

A

prominent ER, golgi apparatus (blue)

37
Q

the nucleus of the serous acini is

A

rounded

38
Q

sublingual gland is predominantly

A

mucous acini

39
Q

mucous acini

A

stain poorly, nucleus is flattened and pushed to the periphery

40
Q

the submandibular gland is

A

mucous and serous

41
Q

what are mixed units

A

mucous acini capped with serous demilunes
