Thymus and
Hypothalamus
Joey Han and Matt Appell
Period 2
Endocrine System
Function:
- regulates mood, growth and development,
metabolism, sexual function and
reproductive processes.
Importance:
- chemicals called hormones control bodily
functions.
- these hormones affect almost every cell
and organ in our body
Thymus
Hypothalamus
Thymus
Hypothalamus
behind the sternum
and between the
lungs
located in the lower,
central part of the
brain
Thymus Gland
Gland
- produce
lymphocytes (Tcells: Thymus
cells), or white
blood cells
- WBC are the
immune system
- produce antibodies
that protect against
bacteria and viruses
Hypothalamus
- responsible for taste
and smell
impulses
- controls heartbeat,
body temperature,
and blood
pressure
- possibly control
emotions.
-Also responsible for
hunger impulses
Hormones
- The thymus secretes thymosin and
thymopoietin
- The hypothalamus secretes GH (growth
hormones), FSH (follicle stimulating
hormone), and prolactin
Hormones of the Thymus
Thymosin
Thymopoietin
- promotes the
maturation of Tcells
- tells T-cells where
to go in the body
Hormones of the Hypothalamus
GH
Stimulates
growth, cell
production,
and cell
reproduction
and
regeneration
FSH
FSH
stimulates
the gonads
to produce
estrogen
and
Prolactin
Prolactin
stimulates the
breasts to
produce milk.
Thymus Gland Diseases
Digeorge Syndrome
- Deletion of 22nd
chromosome.
- Causes thymus
gland to be absent
- Weak immune
system
Thymus Cancer
- Thymoma causes
cancerous cells to
produce.
- Thymic carcinomas
are a different type
of tumors.
- They produce and
grow at a faster
pace.
Hypothalamus Gland Diseases
Hypothalamic Dysfunction
- Could be caused by head traumas,
malnutrition and other causes.
- Can cause headaches, loss of vision, loss
of body hair, and many other symptoms.
- Disruption of the pituitary gland
- Causes drowsiness, moodiness, irritability
and the inability to recover from exercise.
Interesting Facts
Thymus
- The thymus actually
decreases in size
as you age.
- One of the smallest
glands
- After one reaches
puberty, the lining
of the gland turns
to fat
Hypothalamus
- Involved with
puberty
- Controls hormone
release in other
glands.
- The hypothalamus
accounts for 1/300
of the brain weight

Concept Check
1. Without the thymus what happens to the
immune system?
2. Why does Hypothalamus Dysfunctions
cause all these symptoms? What other
gland is it linked up to?
The immune system is weak because there arent T-Cells
Linked up to the Pituitary gland. The Hypothalamus regulates many body functions
3.What happens when the 22nd
chromosome is deleted?
Your thymus is missing. Digeorge system
4. What does the hypothalamus regulate?
Heartbeat, body temperature, and blodd pressure
