Endocrine System - ductless glands that secrete
hormones and release them directly into the bloodstream.
Major glands- Pituitary gland - is the master
• pituitary gland located below the
• pineal hypothalamus in the brain.
• thyroid Regulates hormone production for
• adrenal other glands. Produces growth
• testes hormones and oxytocin.
• ovaries.
Pineal gland - located deep in Thyroid gland - produces thyroxin which affects
the center of the brain. Produces metabolism. Hyperthyroidism causes excitability,
melatonin rod maintains insomnia, and weight loss. Hypothyroidism causes
circadian rhythm. fatigue and weight gain.
Adrenal gland - located above kidneys. Secretes Testes - produce testosterone
corticosteroids which regulate heartbeat, increase
resistance to stress, and muscle development. Secretes Ovaries- produce estrogen and
epinephrine and norepinephrine which control fight or progesterone.
flight.
Heredity - Biological transmitting of traits from parents
to offspring through genes.
Genetics - Subfield of biology that studies heredity.
Behavioral Genetics - Focuses on the contributions of
genes to behavior.
Gene - Basic building blocks of heredity and regulates the development of specific traits.
Chromosome - Humans normally have 46 chromosomes which are made up of DNA.
DNA - Contains our genetic code.
Phenotype - One’s actual development and appearance, as based on one’s genotype
and environmental influences.
