Endocrine Pathology- Exam II Flashcards
Functions of the endocrine system include: (4)
- maintain metabolic equilibrium (homestasis)
- secrete chemical messengers (hormones)
- regulate activities of various organs
- process of feedback inhibition
Maintaining metabolic equilibrium:
homeostasis
Chemical messengers:
hormones
In the process of feedback inhibition, increased activity of target tissue, typically ____ the activate of the gland secreted the stimulating hormone
down regulates
Diseases of under/over production of hormones:
endocrine diseases
Endocrine diseases are associated with development of:
mass lesions
What are the 3 classifications of endocrine diseases?
- too little
- too much
- others: tumors
Tumors of endocrine glands whether benign or malignant, may secrete the hormone native to the gland. These tumors are said to be:
functional tumors
With functional tumors of endocrine glands, it may be the ___ or the _____ that calls attention to the tumor
mass effect; or metabolic effect of the excessive hormone
List the endocrine organs: (6) -
excluding testicles, ovaries, pineal gland, hypothalamus
- anterior pituitary
- posterior pituitary
- thyroid
- parathyroid
- pancreas
- adrenal gland
Where is the pituitary gland located?
base of brain- sella turcica
The pituitary gland is connected to the:
hypothalamus
The pituitary gland is connected to the hypothalamus by:
- stalk composed of axons
- venous plexus
What is the function of the pituitary gland:
central role in regulation of other endocrine glands
What are the two components of the pituitary gland?
- anterior lobe (adenohypophysis)
- posterior lobe (neurohypophysis)
What part of the pituitary gland is the adenohypophysis?
anterior lobe
What part of the pituitary gland is the neurohypophysis?
posterior lobe
How are the diseases of the pituitary gland categorized?
based on what lobe is mainly affected
Label the following image:
A: pons
B: midbrain
C: hypothalamus
D: pituitary gland
What can be seen in the following image?
pituitary gland
Label the following image:
A: hypothalamus
B: anterior pituitary (adenohypophysis)
C: posterior pituitary (neurohypophysis)
What are the different types of cells in the anterior pituitary?
- somatotrophs
- lactotrophs
- corticotrophs
- thyrotrophs
- gonadotrophs
Describe what the following cell of the adenohypophysis produces:
- somatotrophs
- lactotrophs
- corticotrophins
- thyrotrophs
- gonadotrophs
- growth hormone (GH)
- prolactin
- adrenocorticotrophic hormone (ACTH)
- thyroid stimulating hormone (TSH)
- follicle stimulating hormone (FSH) and luteinizing hormone (LH)
The following hormones are produced in the:
- growth hormone (GH)
- prolactin
- adrenocorticotrophic hormone (ACTH)
- thyroid stimulating hormone (TSH)
- follicle stimulating hormone (FSH) and luteinizing hormone (LH)
anterior pituitary (adenohypophysis)
