give me real pituitary gland

I'll read the medical library skill first, then find real pituitary gland images from the textbooks.

Reading File

Now let me search the medical library for pituitary gland images in parallel.

Finding Sources

I can see image URLs in the results. Let me read the relevant sections and fetch the images in parallel.

Let me also get the histology plate and the radiology image for a complete picture.

Here are real pituitary gland images from authoritative medical textbooks:

The Pituitary Gland - Real Textbook Images

1. Anatomy - Sagittal & Coronal Views

Sellar and parasellar anatomy showing the pituitary gland in sagittal (A) and coronal (B) views

Figure: Sellar and parasellar anatomy. A (left): Sagittal view showing the pituitary gland sitting in the sella turcica, connected to the hypothalamus via the infundibulum (stalk). The three parts of the anterior pituitary are visible: pars distalis, pars tuberalis, and pars intermedia. The pars nervosa forms the posterior lobe. B (right): Coronal view showing the gland's key neighbors - the optic chiasm above, the cavernous ICA on each side, cranial nerves III, IV, V1, V2, VI running laterally, and the sphenoid sinus below.

2. Histology - Normal Anterior Pituitary (H&E)

Normal pituitary histology - H&E stain (A) and growth hormone immunostain (B)

Figure 24.1: Normal pituitary histology. (A) H&E stain showing the mixed cell population of the anterior pituitary: the arrow points to an acidophil (eosinophilic cytoplasm - somatotrophs/lactotrophs), the arrowhead points to a basophil (basophilic cytoplasm - gonadotrophs, thyrotrophs, corticotrophs). (B) Immunostain for human growth hormone showing GH-positive somatotrophs highlighted in orange-brown.

3. Histology - Whole Sagittal Section (H&E x50)

Sagittal section of the pituitary gland at low magnification

Plate 21.1: Pituitary gland, sagittal section (H&E x50). The two lobes are clearly demarcated. The large anterior lobe (left - deeper pink/purple, densely cellular) contains the hormone-producing cells. The posterior lobe (right - lighter staining) is neural tissue. The tissue between them is the pars intermedia with the remnant of the Rathke's pouch cleft.

Key Facts

Feature	Detail
Size	~1 cm, ~0.5 g
Location	Sella turcica of the sphenoid bone
Anterior lobe (80%)	Adenohypophysis - secretes GH, PRL, ACTH, TSH, FSH, LH
Posterior lobe (20%)	Neurohypophysis - stores/releases ADH (vasopressin) and oxytocin
Blood supply	Superior & inferior hypophyseal arteries
Clinical concern	Tumors compressing the optic chiasm cause bitemporal hemianopsia

Create an anatomy poster of pituitary anatomy and hormone pathways

Generating Image

A detailed medical anatomy education poster titled "The Pituitary Gland: Anatomy & Hormone Pathways". Top section: A large, accurate sagittal cross-section illustration of the human brain showing the hypothalamus and pituitary gland (hypophysis) sitting in the sella turcica of the sphenoid bone. Label clearly: Hypothalamus, Infundibulum (pituitary stalk), Anterior Pituitary (Adenohypophysis), Posterior Pituitary (Neurohypophysis), Optic Chiasm, Third Ventricle, Sella Turcica, Sphenoid Sinus, Cavernous Sinus, Optic Nerve, Mammillary Body. Middle section: Two side-by-side hormone pathway diagrams: LEFT - "Anterior Pituitary Hormones" showing arrows from the anterior lobe to target organs: - GH (Growth Hormone) → Liver/Muscles/Bones (Growth, IGF-1) - TSH (Thyroid Stimulating Hormone) → Thyroid Gland (T3, T4) - ACTH (Adrenocorticotropic Hormone) → Adrenal Cortex (Cortisol) - FSH & LH (Gonadotropins) → Gonads (Estrogen, Testosterone) - PRL (Prolactin) → Mammary Glands (Milk Production) RIGHT - "Posterior Pituitary Hormones" showing: - ADH (Vasopressin) → Kidneys (Water Reabsorption) and Blood Vessels (Vasoconstriction) - Oxytocin → Uterus (Contractions) and Mammary Glands (Milk Ejection) Note: "Produced in Hypothalamus, Stored & Released from Posterior Pituitary" Bottom section: A small diagram showing the Hypothalamic-Pituitary Axis feedback loop with labels for releasing hormones (CRH, TRH, GnRH, GHRH, Dopamine) and negative feedback arrows. Clean white background, professional medical illustration style, full color with blue and red tones, clearly labeled with arrows, suitable for medical students.

Pituitary Anatomy & Hormone Pathways Poster

Here's your anatomy poster covering:

Anatomy section - sagittal brain view with the pituitary in the sella turcica, labeled infundibulum, optic chiasm, hypothalamus, sphenoid sinus, and both lobes.

Anterior pituitary hormones (adenohypophysis):

GH → liver/bones (growth, IGF-1)
TSH → thyroid (T3/T4)
ACTH → adrenal cortex (cortisol)
FSH/LH → gonads (sex steroids)
PRL → mammary glands (lactation)

Posterior pituitary hormones (neurohypophysis - produced in hypothalamus, stored here):

ADH/Vasopressin → kidneys + blood vessels
Oxytocin → uterus + mammary glands

Feedback loop - showing hypothalamic releasing hormones (CRH, TRH, GnRH, GHRH) and the negative feedback axis.
