Hypothalamus
small organ at the base of the brain
Male hypogonadism
condition where testes do not produce enough amount of testosterone.
Female hypogonadism
condition where ovaries do not produce enough estrogen and progesterone.
Estrogen
female sex hormone that stimulate ovulation.
Menstruation
regular monthly vaginal bloody discharge
Dysmenorrhea
painful cramps in the pelvis or lower
Spermache
onset of sperm development and maturation in male during puberty
Menarche
first menstruation of a woman that occurs during the onset of puberty.
Menopause
gradual decline in menstrual period, stoppage of menstrual period
Perimenopause
point of decline in the female set hormone
effectors
responds to the information by either opposing or enhancing the stimulus.
Homeostasis
refers to the internal stability which is important to living organisms for survival
Receptors
serve to sense changes
Stimuli
the environment that disrupt the state of equilibrium.
Platelet
Assists blood clotting
positive feedback mechanism
maintains the direction of the stimulus and may even speed it up.
glucagon
stimulates the liver to breakdown its glycogen reserves into glucose.
Insulin
stimulates the cells in the various tissues of our body to uptake glucose thus lowering its level in the blood.
negative feedback mechanism
changes the direction of the stimulus by either increasing or decreasing its relative intensity as before
Central Nervous System (cns)
receives and processes such information
afferent neuron
carry the signal away from the body to the central nervous system
Equilibrium
the state wherein the condition of a system is balanced
Natural selection
heritable characteristics which help organisms survive and reproduce successfully become more common in a population over time.
Macroevolution
the evolution over a long period of time which leads to the formation of new species and groups.
microevolution
happens over a shorter of period time and affects just one or a few genes.
Homologous Structures
physical features that are inherited from a common ancestor
Comparative anatomical structures
evidence of evolution are exemplified by the existence of homologous and analogous structures between or among different species
Genetic information
provides strong evidence for evolution at the most basic level because all living organisms share the same genetic code
fossils
preserved remains or traces of living organisms
strata
which fossils are found provide a relative chronological order of their origin
absolute dating
a radiologic method that is based on the half life decay of the radioactive isotope and certain elements
