| Term | Definition |
|---|---|
| Asexual; Budding; Part of parents body separates and makes new individual | Cnidarian Reproduction |
| Females produce offspring from unfertilized eggs | Parthenogenesis |
| Sperm and Eggs | Haploid Gametes |
| Promotes male development | Testosterone |
| Fertilized eggs are deposited outside mothers body to complete development | Oviparious |
| Fertilized eggs are kept within mother to complete development; Young obtain food from yolk | Ovoviparious |
| Young develop within mother and obtain nourishment from her blood | Viviparious |
| Females are sexually receptive to males only around time of ovulation | Estrus |
| Female reproductive cycles involve periodic release of mature ovum | Ovulation |
| Produce testosterone; Converts indifferent external genitalia into penis and scrotum | Leydig Cells |
| Nurse developing germ cells; Help convert spermatozoa by engulfing their extra cytoplasm | Sertoli Cells |
| Male hormone that stimulates anterior pituitary to secrete FSH and LH | GnRH |
| First menstrual cycle | Menarche |
| Human chorionic gonadotropin; Produced by embryo; Picked up on pregnancy test | hCG |
| Fallopian tube, Uterus, Cervix, Vagina | Female Accessory Sex Organs |
| Prevention of pregnancy; ie: abstinance, sperm blockage, sperm destruction, prevention of ovulation | Contraception |
| Pelvic inflammatory disease, endometriosis, premature ovulation | Female Infertility Causes |
| Positioned between plasma membrane and the nucleus of sperm head; sac-like organelle | Acrosome |
| Forms external tissues | Animal Pole |
| Forms internal tissues | Vegetal Pole |
| Eggs with little or no yolk | Holoblastic Cleavage |
| Eggs with large amounts of yolk | Meroblastic Cleavage |
| Process of the cells of the blastula rearrange themselves to form the basic body plan of the embryo | Gastrulation |
| Unites with chorion in birds; Gas exchange; Contributes blood vessels to umbilical cord | Allantois (Extraembryonic Membrane) |
| Encloses amniotic fluid | Amnion (Extraembryonic Membrane) |
| Near eggshell in birds; contributes to placenta in mammals | Chorion (Extraembryonic Membrane) |
| Food source to embryotic birds; Not nutritive | Yolk Sac (Extraembryonic Membrane) |
| Formation of organ in their proper location; Occurs by interaction of cells within and between the 3 germ layers | Organogenesis |
| Exterior; Epidermis, Nervous System, Sense Organs (tongue, skin, eyes) | Ectoderm |
| Middle; Skeleton, muscles, blood vessels, heart, blood, gonads, kidneys, dermis | Mesoderm |
| Inner; Lining of digestive and respiratory tracts, liver, pancreas, thymus, thyroid | Endoderm |
| Dorsal nerve cord | Neurulation |
| Long hollow cylinder formed from cells of the neural plate folding together; Will become brain and spinal cord | Neural Tube |
| Beginning point of invagination | Primitive Streak |
| Synthesis of polypeptides, ribosome, requires RNA | Translation |
| UUA,UGA, UAG; terminate translation | Stop Codons |
| Block of 3 DNA nucleotides corresponding to an amino acid | Codon |
| Allantois, Amnion, Chorion, Yolk Sac | Extraembryonic Membranes |
| Ectoderm, Mesoderm, Endoderm | Primary Germ Layers |
| Condoms, cervical caps, and diaphragms | Three Methods of Sperm Blockage |
| Proestrus, estrus, metestrus, diestrus | Four Phases of Estrous Cycle |
| Oviparity, ovoviviparity, viviparity | Strategies for Development of Internal Vertebrae Fertilization |
| Head, Body, Tail | Structures of mature sperm |
| Monotremes, Marsupials, Placentals | 3 groups of mammals based on how they give birth |
| Lay eggs | Monotremes |
| Birth incompletely developed fetus, mature in mothers pouch | Marsupial |
| Retain young in uterus; Nourished by placenta in mothers blood | Placentals |
| 6 weeks | Fetal Heartbeat Detection |
| Messenger RNA | mRNA |
| When the females fallopian tube is cut and tied | Tubal Ligation |
| When the vas deferens in a males penis is cut and tied | Vasectomy |
| The diploid daughter cell that begins meiosis | Primary Spermatocyte |
| Sex determining region of Y chromosome | SRY |
| Outer surfaces of blastomeres flatten against one another | Compaction |
| In single-celled organisms, an individual organism divides and each part becomes a separate but identical organism | Fission |
| Associated solely with reproduction | Copulation |
| When males release their sperm into egg containing waters | External Fertilization |
| Secretes GnRH | Hypothalamus |
| Animals that regulate their body temperature based on a set point | Homeotherms |
