Question | Answer |
what does mesoderm develop into? | muscle, connective tissue, cartilage and bone, blood and blood vessel, kidney, spleen, gonad, suprarenal cortex |
where is mesoderm develop from? | Primitive streak |
list 3 region of mesoderm | At day 17, the mesoderm is develop into 1) paraxial mesoderm 2) intermediate mesoderm 3) Lateral mesoderm |
Paraxial Mesoderm | it thicken near midline, on each side of notochord and neural plate |
Lateral mesoderm | it remains as think plate at the lateral edge of each side of germ disc -develop into coelom |
Intermediate mesoder | It develops into the component of urinary system |
What is paraxial mesoderm develop into? | Somitomere |
Somitomere differential into two part, which two | 1) The anterior region form beside a neural plate, neuromere, contirbute to Head Mesenchyme 2) the medial and posterior region ==> somites |
Somites | -develope from medial and posterior region of somitomere -first develop in Occipital region, proceed in posterior direction -3 somites pair per day -42-44 pair (4 occipital, 7 cervial, 12 thoracic, 5 saccral and 8-10 occygeal) -they form skeleton |
Which few pair of somites will disappear and does not contribute to skeleton? | first occipital and last 5-7 coccygeal |
What does somites pairs contribute to? | Skeleton |
Which region of somitomere develope into Head mesenchyme | anterior region which form around a neural plate segment (Neuromere) |
Which region of somitomere contribute to skeleton | The medial and posterior which differentiate into Somites |
Which 3 layers does somites differentiate into at week 4? | - Sclerotome - myotome - dermotome |
Sclerotome | -develope from ventral and medial wall of somites which lost cohesion -they are the mesenchymal cell that surround notochard -produce vertebrae by differentiate into bone and cartilage |
which part of somites does dermotome and myotome develop from? | Dermonyotome (the remaining dorsal wall of somites |
what part of body segment does sclerotome, dermotome and myotome contribute to? | -Sclerotome: cartilage and bone of vertebrae -Dermotome: the underlying dermis of skin -Myotome: the muscle attach tot each vertebrae and limb |
