Question Answer
Endocrine Glands A type of gland that secretes chemicals called hormones directly into the blood stream. Endocrine glands play critical role in stimulating growth and regulating bodily functions.
Pituitary Gland The master gland located at the base of the brain that regulates other endocrine gland and produces (growth hormone)(activating hormones
Thyroid(Thyroxin) Affect the growth development of the brain
SSexglands Testes (Testosterone/ Androgens)Ovaries (Estrogen and Progesterone)
Adrenal Glands Support the development of the muscle and bones to contribute to sexual motivation
NNeuron The basic unit of the nerve cell -Dendrites – Cell Body – Axon Synapse
Myelin Sheath Fatty substances insulating the neuron sppeds the transmission of neural impulses
Cephalocaudal Principle The growth that proceeds from the head (Cephlic region) to the tail
Proximodistal principle In development of principle that growth proceeds from the center of the body to the extremities (distial regions)
Orthogenetic Principle Start simple differentiated and integrated pattern of response
Synaptogenesis The growth of synapses or connection between neurons
Synaptic Pruning The removal unnecessary synapse therefore need to make room to between neurons in response to experience
Plasticty Responsive to the individual experiences and it can develop in variety way
Reflexes A unlearned and involuntary automatic response to a stimulus
Behavioral States Ability for infant to develop organized patterns and this shows healthy development
Brain Lnateralization Specialization of two hemisphere of the cerebral cortex of the brain
Left Hemisphere (Brain) Sequential processing, Analyic thought, logic, language, science and math
Right Hemisphere (Brain) Simultaneous processing, Holistic thought, intuition, creativity, art and music
Physical Behavior Are noticeably advanced compared to those infants and toddlers
Adolescent brain (Gray Matter) Made up of primarily of cell bodies and dendrites which undergoes changes inverted pattern across adolecence.
White Matter Consisting of clusters of axon of the steady progression of myelination
Adrenal gland influences Increase the production adrenal androgen sometimes between the ages 6 to 8 in both boys and girls
Adrenrache Circulation of adrenal hormones that contributes to secondary sexually characteristics. A period of increase production of adreanl hormones strain of age that normally precedes the production gonadal hormone.
Gonadal Hormones Are produced by the testes or ovaries are primarily redevelopment of secondary sexual characteristics and sexual maturity
Secular Trend A trend industrialized societies toward earlier maturation and greater body size
Neurogensis The process of generating new neurons across the life span
Male Testosterone Level fluctuate annaully with peak levels detected in spring and lower levels in fall and daily with peak level in the morning. Men with high testosterone to be more sexually active and aggressive than other men
Women Menstural Cycles Accompanied by symptoms such as bloating, moodiness, breast tenderness and headaches during the days just before the menstrual flow
Premenstural Syndrome (PMS) Symptoms experienced shortly before each menstrual period that includes having tender breasts, feeling bloated and being irritable and being moody
Premenstrual Dysphoric Disorder Severe form of premenstural syndrome that include symptoms in addition to physical symptoms associated with menstrual cycles and can be disabling to work and relationship
Female Menopause The ending of a women menstrual cycle
Male Andropause Decreasing the level of tesotrone and symptoms that includes low libido, fatigue and lack of energy erection problems, memory problems and loss pf pubic hair
Reserve Capacity The ability to many organ system to respond to demands for extraordinary output as when the heart and lung work at maximal capacity
Osteoporosis A disease affecting older adults in which bone tissue is lost leaving bone and easily fractured
Osteoarthritis A joint problem among older adults resulting from bones gradual deteriorain of the cartilage that cushions the bones and keeps them from together
Programmed theories Theories that emphsizes of systematic genetic control of aging processes. Which contrast with random error therioes of aging
Average life span A celling on the number of years that any processes. Which contrast with random error theories of aging
Hayflic Limit Found that cell from embryo divide certain number of times adult cells a fewer times than a child.
Random Error theories Theories of aging that call attention to the hazered process that causes damage or errors in cells accumulate and organ system to deteriorate
Free Radicals Chemically unstable by products of metabolism that have unpaired eletron and react with other molecules to produce toxic susbtances that damage cells and contributes to aging
