DEVELOPMENT OF CARDIAC MUSCLE. Cardiac muscle develops from the lateral splanchnic mesoderm, which gives rise to the mesenchyme surrounding the developing heart tube. Heart muscle is recognizable in the fourth week and likely develops through expression of cardia- specific genes.

Heart development. Starts as horseshoe tube cranial to the cranial neural folds, brought to thoracic cavity by cranial folding. BMPs (TGF-( family) plus WNT inhibition induces NKX 2-5, which establishes cardiogenic field. TBX5 (T Box transcription factor) regulates septation. Endocardium = lines heart cavity = same as blood vessels.

The external appearance of the embryo is affected by the formation of the brain, heart, liver, limbs, ear, nose, and eyes. This is the most critical period of development because most of the external and internal structures are formed. Developmental disturbances during this period of time are likely to result in major congenital anomalies of ...

The tail is receding, and the heart is almost fully developed. Teratogens at this point may leave the baby with profound heart problems or a cleft lip. Week 7 -- 7/8 inch, 1/30 ounce; Circumference of an AA battery. This week, the eyes move forward on the face, and the eyelids and tongue begin to form. All essential organs have begun to form.

The circulatory system development increases at a rapid rate. DAY 4: The tongue starts to develop and all body organs are evident. The vascular system is clearly visible. DAY 5: The reproductive organs separate and the sex can be determined. The heart begins to take on a definite shape. The embryo now is obviously a chicken.

The heart tissue is still encased by the visceral layer of pericardium and the parietal layer surrounds it. All that has disintegrated is the dorsal mesocardium. More will be said about the details of the anatomy of the adult pericardial sac in the lecture on the heart. Early Development of the Heart: Endocardial tubes
