SCI 10 WHAT THE HECK IS LIFE ?
SCI 10 LIFE All living things must; move respond to stimulus grow consume and expel reproduce
SCI 10 REPRODUCTION SYSTEM
SCI 10 REPRODUCTIVE system The system of organs involved in sexual reproduction aka. the genital system It also plays a role with fluids, hormones, and pheromones
SCI 10 MALE reproductive system Provides sperm cells
SCI 10 TESTIS Surrounded by the scrotum, it starts to produce sperm at puberty
SCI 10 SCROTUM contracts and relaxes to regulate the temperature of the testes
SCI 10 PENIS organ involved in sexual reproduction and urination
SCI 10 PENIS Composed of erectile tissue, it becomes erect during sexual arousal
SCI 10 EPIDIDYMIS a coiled tube attached to the testes where sperm undergo maturation and storage
SCI 10 VAS DEFERENS a duct that transports mature sperm from the epididymis to the urethra
SCI 10 VAS DEFERENS During ejaculation, the vas deferens contracts, propelling sperm towards the urethra for release
SCI 10 PROSTATE GLAND contribute to semen, enhancing sperm motility and viability
SCI 10 SEMINAL VESICLES produce a significant portion of seminal fluid
SCI 10 SEMINAL VESICLES Their secretion contains fructose and other substances that provide energy and support sperm function
SCI 10 ACTIVITY How important is your reproductive system? Do you place extra care for it? Would you rather have a female’s reproductive system? Only for the boys 1/4
SCI 10 ACTIVITY How important is your reproductive system? Do you place extra care for it? Would you rather have a female’s reproductive system? Only for the boys 1/4
SCI 10 SEXUALLY TRANSMITTED DISEASES
SCI 10 GONORRHEA DO YOU FEEL? Pain or burning sensation during urination Discharge from the penis Swollen or painful testicles Pain or burning sensation during urination Increased vaginal discharge Vaginal bleeding between periods
SCI 10 GONORRHEA caused by the bacterium Neisseria gonorrhoeae
SCI 10 SYPHILIS DO YOU FEEL? painless sore on the genitals or anus rash on the soles, palms swollen glands, fever, hair loss, or fatigue
SCI 10 SYPHILIS caused by the bacterium Treponema pallidum
SCI 10 AIDS DO YOU FEEL? Unexplained weight loss, weakness, and loss of muscle mass Infections on/in your body
SCI 10 AIDS Acquired Immunodeficiency Syndrome Caused by HIV,
SCI 10 HERPES DO YOU FEEL? Painful sores, ulcers, or blisters in the genital or anal area itching in the genital region
SCI 10 HERPES HSV-2 Caused by herpes simplex virus
SCI 10
SCI 10 FROG endocrine system to adapt to specific environments and ecological circumstances.
SCI 10 ENDOCRINE SYSTEM
SCI 10 ENDOCRINE system Maintaining homeostasis within the body requires the coordination of many different systems and organs.
SCI 10 ENDOCRINE system To do that, our bodies undergo a release of chemicals called hormones. Hormones are released by glands.
SCI 10 PITUITARY Aka. “master gland” Located at the base of the brain
SCI 10 PITUITARY Growth hormones regulate body growth (height and weight) and development
SCI 10 PITUITARY Endorphins that act on the nervous system and modulate pain sensation
SCI 10 PITUITARY Affects water retention in kidneys; controls blood pressure Controls production of sex hormones
SCI 10 PITUITARY Affects growth and development; stimulates protein production; affects fat distribution
SCI 10 PITUITARY Stimulates contraction of uterus and milk ducts in the breast
SCI 10 PITUITARY Initiates and maintains milk production in breasts
SCI 10 PITUITARY Stimulates the production and secretion of thyroid hormones
SCI 10 PITUITARY Aka. “master gland”
SCI 10 THYROID is located in the neck, just below the larynx and in front of the trachea
SCI 10 THYROID Controls metabolism; also affects growth, maturation, nervous system activity
SCI 10 THYROID primary function of the thyroid gland is to secrete Triiodothyronine (T3) Thyroxine (T4)
SCI 10 PARA THYROID regulator of blood calcium levels
SCI 10 PARA THYROID PTH increases blood calcium concentrations when calcium ion levels fall below normal.
SCI 10 ADRENAL On top of the kidneys
SCI 10 ADRENAL Aldosterone Regulates salt, water balance, and blood pressure
SCI 10 ADRENAL Corticosteroid acts as an anti-inflammatory; maintains blood sugar levels, blood pressure, and muscle strength
SCI 10 ADRENAL Key in regulating body’s stress response.
SCI 10 PANCREAS Behind the stomach
SCI 10 PANCREAS Insulin Lowers blood sugar levels; stimulates metabolism of glucose, protein, and fat
SCI 10 PINEAL Melatonin Regulates sleep
SCI 10 PINEAL Releases melatonin during night hours to help with sleep. Affects the sleep-wake cycle and eating habits.
SCI 10 GONADS Estrogen
SCI 10 OVARIES Estrogen Affects development of female sexual characteristics and reproductive development
SCI 10 OVARIES Important for functioning of uterus and breasts; also protects bone health
SCI 10 OVARIES Progesterone Stimulates the lining of the uterus for fertilization; prepares the breasts for milk production
SCI 10 TESTIS Testosterone Develop and maintain male sexual characteristics and maturation
SCI 10 PT Integrate Video Create an ad you can insert.
SCI 10 The wrinklier the brain, the more active it is. An active brain tends to be smarter.

SCI 10 NEURONS
SCI 10 NEURON Basic functional units of the nervous system.
SCI 10 NEURON Cell body Contains the nucleus which controls the activities of the cell.
SCI 10 NEURON Dendrite fiberlike structures that acts as receiver and carriers of information
SCI 10 NEURON Axon a long tail-like fiber carries the message away from the body
SCI 10 NEURON Myelin sheath covers the axon which speeds up the travel of the nerve impulses.
SCI 10 NEURON Axon terminal Synapse at the far end, passes on the message to dendrites of other neurons.
SCI 10 TYPES OF NEURONS Sensory Interneuron Motor
SCI 10 NERVE IMPULSE a wave of chemical and electrical signals that are conducted along the neuron
SCI 10 SENSORY gathers information from internal and external environment.
SCI 10 INTERNEURON read and interpret messages sent by sensory neuron connects sensory neurons, motor neurons, and other interneuron
SCI 10 MOTOR conducts impulses away from central nervous system transmits impulses that cause muscles, organs, and glands to respond
SCI 10 TYPES OF NEURONS Summary at pg. 150
SCI 10 NERVOUS SYSTEM DISORDER Neurodegenerative Disorders Neurodevelopmental Disorders Other Neurological Disorders
SCI 10 NEURODEGENERATIVE are illnesses characterized by a loss of nervous system functioning
SCI 10 ALZHEIMER’S DISEASE disruptive memory loss, confusion about time or place, difficulty planning or executing tasks, poor judgment, and personality changes.
SCI 10 PARKINSON’S DISEASE the loss of dopamine neurons
SCI 10 PARKINSON’S DISEASE tremor (shaking of fingers or a limb), slowed movement, speech changes, balance and posture problems, and rigid muscles.
SCI 10 NEURODEVELOPMENTAL occur when the development of the nervous system is disturbed.
SCI 10 AUTISM severity differs from person to person. Autism Spectrum A characteristic symptom of ASD is impaired social skills.
SCI 10 AUTISM problems feeling empathy however, some ASD can prove to be geniuses at their crafts
