  3. Endocrine • How many known hormones are there? • 100 • 15 • 50

  4. Sorry that’s wrong!

  5. Your Right! • There are 50 known hormones affecting the human body. • Hormones affect certain cells, called target cells. Each hormone has a specific shape recognized by the target cells.

  6. Endocrine Two types of Peptide hormones are • cAMP (cyclic AMP) and Inositol Triposphate • FSH and LH • Prolactin and TSH

  7. The Pituitary is the master gland, influencing all other glands. FYI- The posterior lobe of the pituitary gland is actually part of the brain. Genius!

  8. Endocrine • What is the master gland in the body? • Hypothalamus • Pituitary • Thyroid

  9. Amazing! • Peptide hormones are unable to pass through cell membranes and must bind to receptor sites. Two types are cyclic AMP (cAMP) and Inositol Triphosphate.

  10. Endocrine • Female hormone glands are _______ and male hormone glands are _______. • Thyroid and testes • Ovaries and testes • Hypothalamus and thyroid

  11. Great Job! • The Ovaries are the female hormone gland, which produce estrogen and progesterone. • The testes are the male hormone gland in which testosterone is produced.

  12. Endocrine • Which of these are not a hormone found in the pituitary gland? • Endorphins • cAMP • FSH

  13. Correct! cAMP is not one of the many hormones made in the pituitary gland. It is actually a type of peptide hormones. • Endorphins and FSH are both hormones from the pituitary gland.

  14. Nervous • What are the 3 types of neurons? • Sensory, motor, dendrite • Motor, interneurons, resting • Interneurons,motor, sensory

  15. Super! • Sensory, interneurons, and motor are the 3 types of neurons. Sensory takes stimulus to CNS. Interneurons integrate sensory input and motor output. Motor muscles and other glands respond to stimulus.

  16. Nervous • Situation in which nerve is positively charged on outside and negatively charged on inside. • Threshold • Polarization • Depolarization

  17. Great Job! • Polarization is a situation in which nerve is positively charged on outside and negatively charged on inside. • Threshold is lowest point of electrical activity that will initiate depolarization. • Depolarization is the opposite of polarization.

  18. Nervous • What phylum has the simplest nervous system? • Cnidarians • Arthropods • Platyhelminthes

  19. Way to Go! Cnidarians have the simplest nervous system of all the phylum. They have a loosely organized net of nerves.

  20. Nervous • What does acetylcholine do? • Stimulates muscle to contract • Relaxes muscles • Restricts passage of most substances into brain

  21. Great job! • Acetylcholine stimulates muscles to contract. • Cholinesterase relaxes muscles. • Astrocytes, circle capillaries in brain, restricts passage of most substances into brain.

  22. Nervous • What makes up the central nervous system? • Afferent cells and efferent cells • Efferent cells and spinal cord • Spinal cord and brain

  23. Genius! • The central nervous system forms bridge between sensory and motor functions. • It is made of the spinal cord and brain.

  24. Reproductive • What is budding? • Individual grows out from body of original • Breaking of body into several pieces • Regrowth of body or body tissue

  25. Correct! • Budding is when an individual grows out from body of the original individual. • Breaking of the body into several pieces is fragmentation. • Regrowth of body or body tissue is regeneration.

  26. Reproductive • Egg development without being fertilized is? • Hermaphrodite • Parthenogenesis • Viviparity

  27. Your Right! • Parthenogenesis egg development without being fertilized ex. daphnia, ants, bees, wasp • Hermaphrodites have both male and female reproductive parts • Viviparity the young develop in the uterus

  28. Reproductive • Where is the site of the sperm development? • Prostate gland • Vas deferens • testes

  29. Way to go! • Testes are the site of the sperm development. • Prostate gland increases ph of sperm, activates and protects sperm. • Vas deferens tube for sperm transport.

  30. Reproductive • What is the ovary? • Egg development site • Ring of firm tissue surrounding uterine opening • Muscular tube used to receive penis and act as birth passage

  31. Super! • The ovary is the site of egg development. • The ring of firm tissue surrounding uterine opening is the cervix. • The vagina is the muscular tube used to receive penis and act as birth passage.

  32. Reproductive • Which of these is not a mammal? • Monotremes • Oviparous • Marsupials

  33. Great job! • Oviparous is to lay eggs, both internally and externally like birds, fish, reptiles, and amphibians. • Monotremes lay eggs but have fur and produce milk, platypus and echidna. • marsupials have young in uterus but the young crawl into a pouch on the mother examples-kangaroo and opossum.
