Root formation:

Takes place as the crown is completely shaped

Root dentin is influenced by Hertwigs root sheath

Takes place before the appostitional stage of the crown

Include the synthesis of enamel – true for appostitional stage

Is through the formation of the cervical loop

During the 1st week of embryonic development:

Parotid gland:

Myoepithelial cells have contractile ability

The secretory part is composed entirely of serous cells

Myoepithelial cells surrounding acini are secretory cells

Serous acini cells produce granules with mucinogens

Intercalated ducts belong to intralobular ducts

Striated ducts belong to intralobular ducts

Its secretory portion consists of striated ducts

Tooth formation (odontogenesis)

The first stage is formation of dental lamina

Also cap and bell stage are recognized

Odontoblasts and dentin are derivatives of enamel organ

Origin of dentin is mesenchyme, enamel – ectoderm

Which structures are present in dentinal tubules?

Liver:

Largest gland of our body

Liver sinusoids transport blood from vein and arterial system

Bile canaliculi are formed by plasmalemma of adjacent hepatocytes

Select true – development of endocrine organs:

The main mass of the pancreas is made from dorsal pancreatic bud

Langerhans islets arise from cells of excretory pancreatic ducts

Neurohypophysis arise from neuroectoderm of 3rd ventricle

C-cells of thyroid arise from Ultimobranchial body

Endocrine system – find true sentences:

Chief cells of parathyroid glands produce parathyroid hormone (PTH)

Parafollicular or C-cells produce and release calcitonin

Neurohypophysis contains axons of hypothalamic neurons and glial cells

Meissners plexus:

Localized in submucosa of small intestine, stomach, esophagus and intestine

Localized between the circular muscles and mucosa

Brunner’s gland:

In the submucosa layer of duodenum

Secrete alkaline mucous

Lubricate the intestinal walls

Also secrete epidermal growth factors, which inhibits parietal and chief cells of the stomach from secreting acids

Gastrulation:

Is a process that establishes all three germ layers in embryo

As its result, ectoderm, mesoderm and endoderm is being developed

Takes place in 4th week of embryo’s development

Takes place in 3rd week of embryo’s development

Mark true regarding endocrine glands:

Melatonin is secreted by basophilic cells of the pars distalis

The most numerous cells type in human islets of Langerhans is type pp

The most numerous cells type in human islets of Langerhans is type B

Thyroglobulin is stored in colloid of thyroid folliculi

ACTH is secretory product of adrenal zona reticularis cells

ACTH is secretory product of adrenal zona glomerulosa

Peyers patches:

Are found in small intestine

Contains aggreations of lymphoid tissue

Are specific neuronal modifications between two layers of muscles in intestines

Are components of GALT

Large intestine:

Contains a large number of parietal cells

The main function is absorption of water

Has finger-shape villi

Contains DNES cells

Contains numerous and well developed crypts of lieberkuhn

Has long glands

The lip:

Does not contain any glands

Skin region is covered by non-keratinized epithelium

Labial glands are present in the red lip region

The core is composed of skeletal muscle

Contains sebaceous and seromucous gland

Pick up true sentences – hormones:

FSH and LH do not penetrate the plasma membrane

T3 and T4 bind to membrane receptors

Acetylcholine is an example for lipophilic ligand

Insulin binds to intracellular receptor

Insulin binds to membrane receptor

T3 and T4 binds to intracellular receptor

Kupffer cells:

Are present in the vein in the pancreas

Produce food digestive enzymes

Are liver-residing macrophages

Are visible in liver sinusoids

Which of the following statements concerning stomach is/are correct:

Submucosa contains Brunner’s gland

Parietal (oxyntic) cells produce gastric intrinsic factor

The surface epithelium contains goblet cells

Pylorus is a region at gastroesophageal junction
