What is true about the mesenchyme?

Is derived from mesoderm

Is located between the ectoderm and endoderm

Is located between the mesenchyme and endoderm

Is called the 4th germ layer

What is true about somitogenesis

It happens before the initiation of neurulation

It begins at the beginning of the 3rd month of prenatal life

It occurs after the initiation of neurulation

Starts at the beginning of the 3rd week of prenatal life

What is true about dermatome

Is the structure located closer to the neutral tube in embryo

Dermatome progenitors together with cells from the lateral mesoderm will form a dermis

Dermatome cells are differentiated from myotome

Dermatome cells are differentiated from dermomyotome

What is true about the dermomyotome

It is a ventral medial part of the somite

Is also called lateral mesoderm

It is a dorsolateral part of the somite

It’s cells can’t migrate

What is true about the mesoderm

Is located between the mesenchyme and endoderm

Is called 4th germ layer

Is located above the ectoderm

Is one of the three germ layers

Which of the sentence/s about cartilage is/are true

Epiphyseal plates are the hyaline cartilage structures needed for long bones growth

Hyaline cartilage forms the temporal skeleton

Is well vascularized

Is a vascular ( without blood vessels) tissue

Which of the phrase/s concerning osteoclasts is/are true

To its differentiation needs RANKl

Produces cathepsin k

Pumping protons into resorption cavity of bone

Arises from monocytes

What is true about perimysium

It surround the whole muscle

It contain blood vessels

It surround every single muscle fiber

It surrounds a bundle of fibers

What is true about sarcomeres

In smooth muscle sarcomeres are arranged in myofibrils

Are typical for smooth muscles

Contains Z line + ½ I band + A band + ½ I band + Z line

Are present only in smooth muscles

What is true about the skeletal muscle

Actin-myosin binding is triggered by interaction of Ca2+ with troponin subunit C

Phosphorylation of MLCK is responsible for binding actin and myosin

T-tubules are present in the center of the triads

- T-tubules are absent

Which statement regarding epithelium is correct

During the skeletal muscles contraction sarcomeres retain their original length

During the skeletal muscles contraction energy is released from ATP

During the skeletal muscles contraction calcium ions bind to the calmodulin

To trigger a muscle contraction, calcium has to bind to myosin in smooth, skeletal and cardiac muscle cells

Which statement regarding glands is correct

Goblet cell is unicellular gland

Holocrine is sebaceous gland

Salivary glands are always seromucous

Exocrine derive from the epithelium

Which features are typical for epithelium/epithelial cells

Location on the basement membrane/basal lamina

No possibility to regeneration

Polarity

Vascularization

Which statement about holocrine secretion is true

It is also called merocrine secretion

It is characteristic for the sebaceous glands

It consists in turning the entire cell into secretion and its excretion

It is characteristic for the salivary glands

Which of cells located in the connective tissue do originate from the bone marrow

Mast cells

Adipocytes

Fibrocytes

Histiocytes

Which statement regrading synthesis of collagen fibers is correct

Procollagen is precursor for tropollagen

Hydroxylation of proline and lysine is within intracellular environment

Glycosylation of hydroxlysine is within extracellular environment

Hydroxylation of proline and lysine is within extracellular environment

What is true about the dermatome

Is a structure located closer to the ectoderm in developing embryo

It will soon contribute to the development of the skeletal muscles

Dermatome progenitors together with cells from the lateral mesoderm will form an epidermis

Dermatome cells are differentiated from dermomyotome

What is true about somites

They develop from cranial towards the caudal region

They are blocks (segments) of the paraxial mesoderm

None of them disappear

They appear between the 20th and 35th day of prenatal life

Which statement regarding synthesis of collagen fibers are correct

Hydroxylation of proline and lysine is within extracellular environment

Procollagen is precursor for tropocollagen

Hydroxylation of proline and lysine is within intracellular enviorment

Co-factors: O2, Fe, vit. C are needed for the hydroxylation of proline and lysine

Which features are characteristic for multiocular adipose tissue

In human the tissue is important mainly in the first postnatal life

In human newborn the multiocular adipose tissue continues 50% of the body weight

One large, lipid droplet

Many large, lipid droplets

Is it true that osteogenesis

Is the bone development process

During intramembraneous ossification the epiphyseal cartilages are formed

It could be said that bony collar formation is a kind of intramembranous ossification

Could happen thanks intramembranous ossification

What is the characteristic function of mast cells

Influence permeability of blood vessels

Their histamine acts as an anticoagulant

Synthesis if IgE

They produce elestic fibers

Their surface contains receptors for IgE

Storing chemical mediators in granules

What is true about somitogenesis

It happens before the initiation of neutralation

- This is the process of segmentation of the paraxial mesoderm

Is regulated by the so-called segmentation and wave model

- It occurs after the intitation of neurulation

What is true sclerotome

Contains only epithelial like cells

Is derived from ventro-medial somite cells

Scelerotome gives rise to mesoderm

Contains secondary mesenchyme cells
