Thymus and Hypothalamus
Joey Han and Matt AppellPeriod 2
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
Endocrine System
Thymus Hypothalamus
Thymus
behind the sternum and between the lungs
Hypothalamus
located in the lower, central part of the brain
- produce lymphocytes (T-cells: Thymus cells), or white blood cells
- WBC are the immune system
- produce antibodies that protect against bacteria and viruses
Thymus Gland Hypothalamus Gland
- responsible for taste and smell impulses
- controls heartbeat, body temperature, and blood pressure
- possibly control emotions.
-Also responsible for hunger impulses
- Linked to the pituitary glands
- The thymus secretes thymosin and thymopoietin
- The hypothalamus secretes GH (growth
hormones), FSH (follicle stimulating hormone), and prolactin
Hormones
Thymosin
- promotes the maturation of T-cells
Hormones of the Thymus
Thymopoietin
- tells T-cells where to go in the body
Hormones of the Hypothalamus
GH FSH Prolactin
Stimulates growth, cell production, and cell reproduction and regeneration
FSH stimulates the gonads to produce estrogen and androgen.
Prolactin stimulates the breasts to produce milk.
Digeorge Syndrome- Deletion of 22nd
chromosome.- Causes thymus
gland to be absent- Weak immune
system
Thymus Gland Diseases
Thymus Cancer- Thymoma causes
cancerous cells to produce.
- Thymic carcinomas are a different type of tumors.
- They produce and grow at a faster pace.
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.
Hypothalamus Gland Diseases
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

Bibliography
1. Without the thymus what happens to the immune system? The immune system is weak because there arent T-Cells
2. Why does Hypothalamus Dysfunctions cause all these symptoms? What other gland is it linked up to?
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
