Outer epithelium
Stellate reticulum
Inner epithelium
Tooth formation (odontogenesis)
The first stage is formation of dental lamina

Odontoblasts and dentin are derivatives of enamel organ
Origin of dentin is mesenchyme, enamel – ectoderm
Which structures are present in dentinal tubules?
Unmyelinated axons
Tissue fluid
Blood vessels
Tome ̝s fibers – another name for odontoblast processes
Odontoblasts
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
Which of the following endocrine glands develop from neuroectoderm:
Neurohypophysis
Adrenal medulla
C-cells in thyroid
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
