Lab Exam 1 Flashcards
Has distinctive “pools” of colloid surrounded by follicle cells (simple cuboidal epithelium).
Thyroid gland
Looks like cobblestone street. The “stones” are arranged in distinctive columns are the colloid and the “mortar” is the follicle cells.
Thyroid gland
Hormones:
Calcitonin Thyroid Hormones (T4 & T3)

PARATHYROID GLAND
Indistinct compared to the other glands. May see the thyroid gland in the field of view on____ power.
low
Hormones:

Parathyroid gland
PANCREAS
The collections of lighter stained cells ____surrounded by “grape like” darker stained cells_____
(Islets), (Acini)
Pancreas
Hormones:

Glucagon
Has a medulla and a cortex. The middle layer of the cortex has cells that are arranged in distinctive columns
Adrenal gland (suprarenal)
ADRENAL GLAND (SUPRARENAL)
Hormones:
Medulla
Epinephrine and nonepinephrine
ADRENAL GLAND (SUPRARENAL)
Hormones

Androgens
TESTIS
The_____ look like kiwis and
the_____ look like the seeds in the kiwi.
seminiferous tubules, spermatozoa
The cells between the kiwis are_____44.
interstitial cells
TESTIS
Hormones
Testosterone
Looks like the cartoon representations in the text.
The_____ is the LARGE structure. You may or may not be able to view the ovum
mature follicle
OVARY
Hormones
Estrogen
Progesterone
PITUITARY GLAND (HYPOPHYSIS).
Has two parts:
Anterior pituitary (adenohypophysis), Posterior pituitary (neurohypophysis)
This side stains easily and the
appears darker. Produces and releases hormones.
Anterior pituitary (adenohypophysis)
The nervous tissue is hard to stain and you can almost see
the hypothalamic hypophyseal tract
Posterior pituitary (neurohypiphysis)
Hormones:
Adenohypophysis
FSH & LH
ACTH
TSH
GH
Prolactin
Hormones
Neurohypophysis
ADH
Oxytocin
Granulocytes
Basophils, Neutrophils, Eosinophils
Agranulocytes
Lymphocytes, Monocytes
releases chemical that mediate the inflammatory response
Basophils
phagocytes (acute infections)
Neutrophils
allergies and parasitic infections
Eosinophils
responsible for acquired immunity
Lymphocytes
phagocyte (chronic infections)
Monocytes
a foreign substance that enters your body. This can include bacteria, viruses, fungi, allergens, venom and other various toxins. They help your immune system detect threats, which helps keep you safe.
Antigen
a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood.
Antibody
Tiny vessels, random tissues of most organs in your body they transport and filter, lymphatic fluid from your body, cells and tissues. Lymphatic pathways begin in the
Lymphatic capillaries
are lymphatic capillaries in the lining of the small intestine that are important in transporting lipids absorb from digested foods
Lacteals
A thin tube that carries lymph (lymphatic fluid) and white blood cells through the lymphatic system
Lymphatic vessels
Drain into the junction of the internal jugular and subclavian veins. Receives lymph from the right side of the head, neck, arm, thoracic region. 
Right lymphatic duct
The largest of the lymphatic organs
Spleen
Is the site of T cell maturation. It is located in the mediastinum and is composed of two lobes, each containing many thymic lobules. 
Thymus
Are small, encapsulated structures that contain lymphocytes, macrophages, dendritic cells . They are connected by lymphatic vessels, with the majority clustered in the cervical, axillary, and inguinal areas of the body.
Lymph nodes
vessels flow into a lymph node and carry unfiltered lymph fluid.
Afferent vessesls
flow out of a lymph node and carry filtered lymph fluid.
Efferent vessels
the abdominal origin of the thoracic duct, and it receives the bilateral lumbar lymphatic trunks. It is located in the retrocrural space, to the right side and behind of the abdominal aorta.
Cisterna chyli
Transports lymph back into the circulatory system
Thoracic duct
