Transcript Endocrine System

BODY SYSTEMS
EQ II – 3.01

Consists of ductless glands producing internal secretions called
hormones that control and promote homeostasis (balance)
between physiologic functions.

Hormones regulate bodily reactions by slowing or speeding the
rate or organ functions.

The pituitary and hypothalamus work together to coordinate the
endocrine and nervous systems.

The hypothalamus is the center of the autonomic nervous
system.

The hypothalamus releases hormones that regulate the
pituitary.
ENDOCRINE SYSTEM

Some of the hormones and the glands of their origin are:

Hypothalamus: ADH (vasopressin) is the trauma hormone,
oxytocin controls lactation and reproductive phases of the
mare.

Pituitary: FSH stimulates the ovaries of the mare and sperm
production in the male, LH stimulates secretion of estrogen in
the mare and testosterone in the male, LTH (prolactin)
promotes lactation once the mammary system has been
primed by estrogen and progesterone, TSH stimulates the
thyroid gland to release thyroxin that regulates the body
metabolism.

Pancreas: Insulin regulates glucose metabolism

ENDOCRINE SYSTEM

Using pipe cleaners, construct a model of the equine endocrine
system.

Glue pipe cleaners to a sheet of paper and label each piece
and list it’s function. Be sure to use different colored pipe cleaners
for each component.
ASSIGNMENT

After completing your endocrine model, please complete the
open notes quiz. This will be turned in for a grade.

Friday we will take our baseline exam and finish Secretariat.

Monday we will review the systems you have learned about and
start talking about the reproductive tract.
