Adrenal Gland

Question 1

Parts of the adrenal gland

Answer 1

Capsule, cortex, medulla, sinusoids

Question 2

Three zones of the cortex and where they are

Answer 2

Zona multiformis (glomerulus; outermost)
Zona fasiculata (middle)
Zona reticularis (innermost)

Question 3

Describe cells of the zona glomerulosa/multiformis

Answer 3

Columnar cells arranged in an arc-like formation with convexity near the capsule

Question 4

Describe the zona fasiculata

Answer 4

Consists of cuboidal or columnar cells arranged in radial cords
Numerous vacuoles that once contained lipid can be seen in fasiculata cells

Question 5

Describe zona reticularis

Answer 5

Consists of anastomosing cords of cells that contain fewer lipid vacuoles

Question 6

Describe characteristics of the medulla

Answer 6

Granular cytoplasms of cells
Central vein present
Neurons can be found scattered of the autonomic nervous system

Question 7

Since the cells of the medulla and cortex interdigitate, what may be amongs the chromaffin cells

Answer 7

Projections of the zona reticularis

Question 8

Describe the adrenal gland of the chicken

Answer 8

Lack of organization
Cords of cortical cells in pink are mixed with cords of medullary cells in purple
A rich capillary or arteriole/venule supply is evident and ganglion is present at one pole
