in the primordial follicle stage

Huxley's layer

the esophageal glands proper resemble glands from the cardiac region of the stomach

Keratin filaments embedded in trichohyalin

stratified squamous nonkeratinized

Keratin filaments and trichohyalin granules

The thinnest region of the interalveolar septum, where gases can be exchanged

A brief period of involution, the anagen phase

The papillary layer of the dermis contains the capillary network which supplies the epidermis.

The excretory ducts of sweat gland are lined by a simple squamous epithelium.

11 nm

Adenohypophysis

The most superficial layer lies just deep to the pia mater;

Continuous capillaries, supplied by pulmonary artery and drained by the pulmonary vein

Neurohypophisis

Molecules greater than 69,000 Da are trapped by the basal lamina

is initiated when the hormone level is inadequate to elicit a sufficient metabolic response in the target

It is the pseudostratified epithelial lining

Luteinizing hormone

They become narrower in diameter and their population of alveoli increases

Hypophyseal portal veins

They increase the velocity of the movement of chyme along the alimentary canal

Corticotrophs

Adenohypophysis

it is composed of two leaflets, each having a thin fold of intima jutting out from the wall

Somatotropin producing cells are acidophils

Parafollicular cells

Hypodermis

2, 3, 4

Are formed by the coupling of an MIT and a DIT or of two DITs, respectively.

In response to TSH

In terminal ganglia

1, 2

In lens fibers

Zona fasciculata

From neural crest cells

pseudostratified

The left suprarenal vein drain into the vena cava inferior

it responds in a specific manner; and has immunological memory

In the medulla

Zona reticularis

in lamina propria of esophagus

helical arteries

its arteries are smaller than the veins

in the exocrine pancreas

it is include the seromucous glands in all its regions

1, 5

Neurohypophysis

Primary bronchi

2, 3, 4, 5

Their wall contain large number of ciliated and goblet cells

They are believed to protect the alveolar epithelium

Angiotensin II and ACTH

They are merely a continuous sequence of alveoli

They located in anterior one third of the ciliary body and radiate out from a central core of connective tissue

The epithelial lining of trachea ranges from ciliated simple columnar with occasional goblet cells

urine pass down the ureter because of gravitational forces

five epidermal layers

Single smooth muscle cell, embedded in type III collagen

They reinforce the alveolar duct, stabilizing it somewhat

the theca interna cells

The air spaces of the two alveoli do not communicate with each other

lamina propria

activin produced by the primary oocyte.

They arise from the lymphocytes gain access to the pulmonary interstitium

A broad, lattice-like network known as tubular myelin

Matrix

Decreases surface tension, prevents the collapse of the alveolus
