organizational hypothesis
Differential hormone exposure early in life organizes neural circuitry underlying sexually dimorphic behaviors
actiavation hypothesis
differential hormone exposure in adulthood activates this circuitry and results in expression of sexually dimorphic behaviors
estrogen, immobile position with arched back and deflected tail (allows males to mount/mate)
revised conclusion of o/a hypothesis
testosterone acts during a critical period of development to "program" adult sex behavior
sexual dimophism related to sexual partners
more dimorphic = polygamous, less dimorphic monogomous
intrasexual selection
males compete with each other for females
intersexual selection
females choose males with most attractive traits
sexual selection
a form of natural selection, individuals differ in their ability to compete for and/or attract potential mates
XXY Klinefelter syndrome
contains SRY, masculinazation occurs, long limbs,
between axon and dendrite, an action potential releases neaurotransmitters
causing a charge in potential
neurotransmitter binds itself to the receptor sites on the dendrites of the next neuron
the neurotransmitter returns to the synpatic knob
peripheral nervous system
spinal and cranium nerves
somatic system
connects CNS to voluntary muscles
autonomic system
connects CNS to involuntary muscles
sympathetic system
readies the body for energy use
parasympathetic system
restores the body
Synthesized in hypothalamus, Increases wakefulness,
Food intake, and sexual arousal
Antidiuretic Hormone (ADH)
Synthesized in the hypothalamus, kidneys, stored in posterior pituitary, In blood, Maintains homeostasis, Involved in social behaviors
Follicle Stimulating Hormone (FSH) Luteinizing Hormone (LH
releasing hormone (GnRH), Controls ovulation
controls hormone secretions
anterior pituatary
growth, secreted by thyroid
posterior pituiatary
water and salt balance
adrenal glands
emotional arousal, inflammatory reactions, salt and carb metabolism
pineal gland
reproductive maturity, body rythms
multiple endocrine glands working together
energy, appetitie, metabolism
regulates sugar levels
releases Calcitonin, growth and development
releases Parathyroid Hormone (PTH)
Stimulates uterine contraction during labor
Stimulates Release of milk in response to suckling Milk production requires Prolactin
Adrenocorticotropin Hormone (ACTH)
adrenal cortex/anterior pituatary gland, increases prodcution of cortisol in response to stress
morphological sex
dependent on external genitals
turner syndrome
XO chromosomes, Unambiguously sexed as girls at birth, ovaries do not produce steroid hormones
Congenital Adrenal Hyperplasia (CAH)
adrenal glands produce high concentrations of androgens (male sex hormones), masculinization in females
Multiple "types" of the same sex
Kallmann Syndrome
Decreased release of GnRH, Males with it have no sense of smell (ansomic)
recurrent =learning, efferent=production, organized by estrogens, activated by androgens,
