Question
During blood loss, release of EPO hormone will be increased/decreased. Active transport of solutes from blood into the rental tubular fluid is called (filtration/secretion). Secretions of juxtaglomerular complex are: EPO and When bloo starts to become too acidic, the kidneys respond by: Metabolic alkalosis occurs when: the kidneys excrete a decreased amount of bicarbonate, and they have not started the compensation yet. (This statement is true). When water is lost,. but electrolytes are retained, water moves from ICF to ECR, Why? During spermatogenesis, each primary spermatocyte produces four spermatids/spermatocytes/spermatogoria You should known which stage is haploid or diploid in both spermatogenesis and oogenesis. What are the functions of epididymis, nurse cells end seminiferous tubules? A boy has a genetic imitation such that FSM is not produced. but LH is normal After the boy grows to maturity, it is likely he will be sterile. True/False In the luteal phase othe ovarian cycle, the ovary is under gong the formation of a primary follicle or a corpus luteum? While ovary is undergoing luteal phase, what specific phase is happening during the uterine cycle at that time? What causes a surge in LM during ovarian cycle? FSH/estroger/progesterone. The surge in the LH that occurs during middle of the ovarian cycle is caused by a surge in hormone Site of fertilization? Isthumus/ampulla/uterus?? During gestation, powerful uterine contractions are suppressed by elevated levels of: progesterone The hormone that is the basis for a pregnancy test is: Human shot ionic gonadotropin hormone Milk ejection or letdown reflex is stimulated by which hormone associated with pregnancy? interstitial cells (in the testes) are simulated by (LH/FSH) and release (estrogen/testosterone/aldosterone) in response. *Know the stages of labor* *Know the difference between Mitosis and Meiosis steps and terms involved for both male and female.*Explanation / Answer
72. increased.
73. tubular secretion.
74. renin
75. synthesizing and reabsorbing bicarbonate ions while secreting H+.
76. False
77. osmosis moves water from the ICF to the ECF because osmolarity of the ECF rises, both the ECF and the ICF become more concentrated, and there is an decrease in the volume of the ICF.
78. spermatocytes.
79. No.
80. Epididymis
Near the top of the testis is the head of the epididymis, which stores sperm until it is ready to undergo maturation. Next is the body, a long, twisted tube where the sperm matures. This maturation takes approximately one week. Last is the tail, which connects to the deferent duct, also referred to as the ductus deferens or vas deferens. From here, the sperm is transported to the ejaculatory duct.Partially surrounding and separating the epididymis from the testis is a thin sheet of tissue referred to as the tunica vaginalis. The walls of the epididymis are lined in pseudostratified columnar epithelial tissue, meaning that the arrangement of the cells gives the appearance of two layers, although it is only one.
Nurse cell
In respect to invertebrates, nurse cells are polytenic germline cells that contribute to the development of the oocyte, producing multiplenuclei. In fruit flies (Drosophila), nurse cells surround the developing oocyte and synthesize proteins and RNAs that are to be deposited in it. They contain about 250-500 nuclei, all 15 of them in all oocytes creating 5,000 nuclei in total. They dump their cytoplasm containing the nuclei into the oocyte via ring channels.In mycology, a nurse cell is any hyphae that supplies food material to spores that have detached from the basidia; used especially in reference to taxa from the family.Nurse cells are specialized macrophages residing in the bone marrow that assist in the development of red blood cells. They absorb the nuclei of immature red blood cells and may provide growth factors to help the red blood cells mature. In the bone marrow, immature red blood cells (erythroblasts) can be seen grouped in a cluster around a nurse cell.
Seminiferous tubules
The seminiferous tubules function to produce sperm, maintain the sperm, and to store the sperm. During the process of meiosis the sertoli cells that line the seminiferous tubules undergo the process of differentiation to be converted into sperm.Seminiferous tubules are structures located in the male sex organ called the testis. Meiosis in males occurs in the seminiferous tubules. This means that the seminiferous tubules are crucial in the process of reproduction. The seminiferous tubules are found inside the testes. They consist of a network of tubes that are lined with a type of cell known as a sertoli cells. Sertoli cells are long columnar cells that are differentiated during the process of meiosis to form sperm.
