Glands of stomach:

Pyloric and cardia glands secrete mucous

Parietal cells are ion-pumping cells

Chief cells contain granules with pepsin

Pharyngeal arches:

Appear in 4th or 5th week of development

Core contain mesenchyme

Pharyngeal arches appear in the 9th week of development

Arch is covered outside: ectoderm inside: endoderm

Contribute to the formation of the nec

The gallbladder:

Doesn’t have a submucosa layer

Release bile into duodenum after a meal

Is lined with simple columnar epithelium

The part located close to the liver does not have a adventitia

The part located close to the liver do not have a serosa

Portal lobule

Drains bile from hepatocytes to the bile duct

Drains blood from the hepatic artery to central vein

Removes deoxygenated blood from the hepatocytes

Supplies oxygenated blood to the hepatocytes

Drains blood from the portal vein to the hepatic artery

Salivary glands:

Minor are covered by connective tissue capsule

Parotid does not contain mucous tubules

Submandibular and sublingual is tubuloacinar

Its plasmocytes produce lgA

Hypophysis

Pituicytes are cells of neurohypophysis

In neurohypophysis are unmyelinated axons

In pars intermedia POMC is produced

Oxytocin is stored in Herrings bodies

Neurohypophysis contains axons of hypothalamic neurons and glial cells

Choose correct pair (gland or part of gland and hormone)

Glucagon – Alpha cells of Langerhans islets

Calcitonin – C cells of thyroid

Adrenalin (epinephrine) – adrenal zona fasciulata

Triiodothyronine – parathyroid gland

Cholesterol – adrenal zona glomerulosa

Glucocorticosteroid – adrenal zona glomerulosa

Glucocorticosteroid – adrenal zona fasciulata

Triiodothyronine – thyroid

Adrenalin (epinephrine) – adrenal medulla

Adrenal glands:

Medulla releases and accumulates catecholamine

Medulla releases and accumulates epinephrine

Medulla releases and accumulates norepinephrine

Mark properly matched cell and its function:

Goblet cell – mucous production

Enteroendocrine cells – produce hormones

Enterocyte – production and exocytosis of chylomicrons

Paneth cell – defensins production

Enteroendocrine cell – mucous production

Enterocytes – choose correct:

Their apical cell membrane form brush border

Are the epithelial cells of intestine

Are involved in lipid absorption

Accumulate many small lipid droplets in vesicle of the SER

Teeth:

Dental pulp contains odontoblasts

Dental pulp is highly vascularized

Dental pulp consists of collagen fibrils

Enamel is mostly composed of calcium hydroxyapatite

Dental pulp consists of fibroblasts

The organic matrix of dentin contains only type III collagen

The organic matrix of dentin contains only type I collagen

Mark the true about the mucosa:

Comprises a lamina propria

Is often called the mucous membrane

Contains MALT elements (mucosa-associated-lymphoid-tissue)

Find truth – oral cavity:

Striated muscle in the lips makes these structures highly mobile for ingestion and speech

Mark the correct sentences about von Ebner ̝s glands

Find environmental influences, which may cause orofacial clefting:

Pharyngeal clefts:

1st pair of clefts give rise to auditory meatus

2nd, 3rd, 4th clefts lose contact with the outside

Cervical sinus is formed by all clefts

Cervical sinus is created by the 2nd, 3rd and 4th clefts

1st, 2nd, 3rd clefts lose contact with the outside

The 5-week embryo is characterized by the presence of four pairs of clefts

Face development:

Upper lip is formed by 4 prominences

Upper lip is fomed by 2 lateral nasal prominences

Facial prominences appear at the end of the 4th week

Nasal placodes are local thickening of the surface ectoderm on both sides of frontonasal eminences

Nasal placodes is a part of endodermal epithelium

The lower lip and jaw are formed from the mandibular prominences

Nasal placodes is a part of ectoderm

Which structures undergo intense involution (degeneration) during postnatal life?:

Fetal cortex of adrenal glands

Pineal gland

Parathyroid glands – select true:

Inferior parathyroid glands develop from 4rd pharyngeal pouch (10th week)

Inferior parathyroid glands develop from 3rd pharyngeal pouch (4th week)

Inferior parathyroid glands develop from 3rd pharyngeal pouch (5th week)

Superior parathyroid glands develop from 5th pharyngeal pouch

Superior parathyroid glands develop from 4th pharyngeal pouch
