Type of hypothyroidism caused by a disease in the pituitary gland
Secondary hypothyroidism
State of being in heat
Estrus
A compound that originates outside of the body, a drug.
Exogenous compounds
Naturally occurring hormone
Endogenous
Part of the estrous cycle that runs from the development of the follicle to lysis of the follicle
Follicular phase
Part of the estrous cycle controlled by the CL
Luteal phase
Thyroid condition caused by a lack of iodine and not a malfunction with the thyroid gland
Goiter
Muscular layer of the uterus
Myometrium
Creation of glucose from amino acids (proteins)
Gluconeogenesis
Can cause cancer
Carcinogenic
Disease treated by sulfonylurea compounds
Oral medications used to lower blood glucose in diabetic patients
Breakdown of glycogen stores in the liver
Glycogenolysis
Lyses the corpus luteum
Prostaglandin
Stimulates secretion of T3 and T4
Thyroid secreting hormone
Hormone secreted by the developing follicles on the ovary
Estrogen
Hormones that predisposes the uterus to pyometra
Progesterone
Estrogen
Hormone that triggers development of cells that hold the ovum
Follicle stimulating hormone
Side effects in the mare include bronchoconstriction, colic, and premature abortion
Dinoprost tromethamine, cloprostenol, or fenprostalene
Used to treat urinary incontinence in spayed female dogs
Diethylstillbestrol (DES)
Used to bring cattle in the luteal phase of estrous cycle back into estrus; not effective in the follicular phase
Dinoprost tromethamine (Lutalyse)
Hormone naturally produced by the CL
Progesterone
Hormone that naturally lyses the mature follicle and releases the egg
LH
Form of thyroid drug most commonly used to treat hypothyroidism
Levothyroxine
Level is decreased in cats with primary hyperthyroidism
TSH and TRH
DOC for maintaining control of diabetes mellitus in the dog; intermediate-acting insulin
NPH insulin
Short-term treatment of choice for hyperglycemia in dogs with uncontrolled diabetes mellitus; brings glucose levels down quickly given IV
Regular or crystalline insulin
Hormone that maintains pregnant state of the uterus
Progesterone
Hormone associated with behavioral signs of heat
Estrogen
Given to help a flaccid, pregnant uterus contract during labor
Oxytocin
Given to transitional estrus mares over several days to imitate diestrus, then stopped to stimulate the normal regression of the CL and hopefully initiate the follicular phase
Altrenogest
Used to decrease hyperglycemic condition in some cats with diabetes, given orally
Glipizide; sulfonylurea compound
Sometimes given to mares to attempt to maintain pregnancy, rarely successful other than in mares that are naturally lacking this hormone
Progesterone compounds
Hormone that directly stimulates the thyroid to produce and release hormones
TSH from pituitary
Thyroid hormone that actually causes the changes inside the cell
T3
Thyroid hormone that allows local tissue regulation of its thyroid hormone need
T4
Hormone that causes the release of FSH and LH to start the follicular phase
GnRH
Hormone that causes development of ovarian cells that produce estrogen
FSH
Hormone that stimulates the development of the CL from follicular cells
LH
Hormone released by the pituitary when the fetus enters the birth canal, causes forceful uterine contractions
Oxytocin
Hormone released by the fetus to begin the steps leading to parturition
ACTH
A control, not a cure for hyperthyroidism; keeps thyroid from synthesizing thyroid hormones
Methimazole
Compound that destroys the feline thyroid tumor in feline hyperthyroidism
131I
Used to decrease the heart rate of a hyperthyroid cat but doesnt effect the excessive concentrations of T3 and T4
Propranolol
Was used to prevent pregnancy in the dog by suppressing release of GnRH, FSH, and LH
Megestrol acetate
Prevents a mare from coming into foal heat by inhibiting the follicular phase of estrous cycle, its a progestin
Altrenogest
Can cause open-cervix pyometra in the dog 2-4 weeks after administration can also cause aplastic anemia
Estrogens
Long-lasting insulin
Ultralente, PZI insulin
Used to synchronize the estrus cycle of animals in the lutral phase by terminating the luteal phase and bringing them back into the folllicular phase
Dinoprost tromethamine
Used to terminate pregnancy in mares; much species variation in its effectiveness
Dinoprost tromethamine
Excessive production of thyroid hormone
Hyperthyroidism
Low production of the thyroid hormone
Hypothyroidism
Decrease in thyroid hormone associated with disease or destruction of the thyroid gland
Primary hypothyroidism
Thyroid gland is normal, pituitary is also normal but the hypothalamus is unable to produce TRH
Tertiary hypothyroidism
Procedure used in cats to best treat hyperthyroidism and is the removal of the thyroid gland
Thyroidectomy
Type of diabetes characterized by a decrease in insulin and related to the number of functional beta cells
Insulin dependent diabetes mellitus (IDDM)
Type of diabetes resulted from a decreased effectiveness of insulin even though the beta cells are capable of producing adequate insulin
Non-insulin dependent diabetes mellitus (NIDDM)
Used to describe the noun cycle
Estrous
Synthesized drugs that mimic progestins
Progestagen
Suppression of blood cell production by the bone marrow, decrease in bone marrow cells
Aplastic anemia
Reproductive hormones decrease to minimal amounts causing the mare to stop cycling and enter a period called _____
Seasonal anestrus
Difficult labor
Dystocia
TRUE OR FALSE. Overdose of insulin will result in hyperglycemia
True
TRUE OF FALSE. Compared with humans dogs are very susceptible to thyrotoxicosis
False
TRUE OR FALSE. General rule, cats need longer acting insulin than dogs
True
Levothyroxine
Use, contraindications, side effects
