Early Fetal
Now observe in these cross-sections of the week 10 fetal head the structure and position of endocrine structures in the head and neck. It is also a time to observe the position of the cochlea.
Stage 22 Selected
A7 CN5 and endocrine | |
B2 pituitary | |
C2 pharynx Overview of embryo (stage 22) neck region where high power sections is from in C3. Thyroid gland at top of image lying anterior and extending lateral to the trachea. | |
C3 trachea and thyroid Thyroid gland. | |
C5 thorax Overview of embryo (stage 22) chest region where high power sections is from in C6. Thymus gland at top of image anterior to section through aortic arch. | |
C6 thymus Thymus gland. | |
E6 gastrointestinal Overview of embryo (stage 22) at the level of the liver where adrenals are seen. | |
F3 adrenal gland Fetal and permanent adrenal cortex. The medulla of the adrenal gland is of neural crest origin and it is not yet encapsulated by the cortex. |
