BIO 255 exam 1 Iowa state Questions and Answers Cytology refers to the study of cells and their internal structures tissues are composed of cells which is an organ of the reproductive system uterus which is an organ of the circulatory system arterioles in the anatomical position, you neck is ______ to your femoral region superior which term means "nearer the midline" medial which term means "away from the head" inferior the midsagittal plane divides the body into equal right and left sides The heart lies in the ________ cavity. Ventral pericardial the parietal pleura is the serous membrane lining the pleural cavity the stomach is located in which abdonimalopelvic quadrant left upper which best describes the plasma membranes your cell phospholipid bilayer with embedded proteins and cholesterol which two work to hold cells together desmosomes and adherins junctions the main solute of the cytoplasm is proteins which structure tags proteins so they are delivered to their proper locations Golgi body Mitochondria contain some of the genetic code necessary for their own duplication which would be haploid human eggs which is NOT a direct product of mitosis sperm the cell makes DNA during the ___ stage of the cell cycle S chromosomes align at the cell equator during metaphase Although mitosis produces many cells with cancer, the cells are usually not functional. true You can move your bones by using ___ tissues muscle a tissue brining a stimulus to your stomach causing it to churn and mix the food you have eaten would be a[n] ______ tissue nervous which tissue is best suited controlling which chemicals in food are absorbed by your digestive tract simple columnar a single layer of tall and narrow cells, with nuclei at various levels and interspersed goblet cells is found lining your respiratory tract. This is a pseudo stratified columnar epithelium which tissue provides strength while allowing compression? this tissue is found in your intervertebral disks fibrocartilage which is composed of unstriated spindle-shaped cells under involuntary control smooth muscle which type of cells protect and support other cells in your brain neuroglia an exocrine gland that discharges a secretion from the border of a cell is a merocrine gland embryonic connective tissue that can differentiate to become all other connective tissue types is composed of mesenchyme which membrane is composed of keratinized squamous epithelium with dermis connective tissue beneath? in tissue repair, scar tissue develops from the stroma the ovum is a gamete Cleavage as part of embryonic development is distinctive because it involves ________. cell division by mitosis with little or no growth between successive divisions the embryonic membrane formed by the chorion of the embryo and the maternal endometrium is the placenta? Muscle tissue is formed by the ________. mesoderm which is NOT a function of the skin major excretory organ which layer of the epidermis comprises the outermost layer and provides most of the epidermal thickness stratum corneum which layer of the epidermis is deepest and the site of rapid mitosis to produce the more superficial cells stratum basale which skin derivative is found only in the epidermal layer and not surrounded by another skin layer the coarse long hair of your scalp is terminal In instances with elevated blood supply, irritation can promote hair growth (true/false) true the dermis is derived from the mesoderm Mobob has primary ciliary diskinesia. He has severe respiratory problems. He is sterile because the tails of his sperm do not move. What cellular structures do not work in Mobob? microtubules what determines the shape of anatomical structures their functions embryology refers to study of developmental changes from fertilization to birth molecules are composed of atoms which is one role of the digestive system Absorbs nutrients from the diet In proper anatomical terminology, the skin is ___ to the lungs. superficial which is NOT a function of cell plasma membranes intercellular adhesion cell junctions providing an impermeable junction encircling the cell, which inhibits movement between cells, are tight junctions the plasma membrane of a cell is directly surrounding the cytoplasm which structure may serve as a site of calcium ion storage smooth endoplasmic reticulum which structure makes proteins that will be part of cell membranes rough endoplasmic reticulum Which can be called "reductive division" because the daughter cells produced have a reduction in the number of their chromosomes, from diploid to haploid? Meiosis the cell prepares fro mitosis during the ____ stage of the cell cycle G2 cytokinesis begins at the same time as telophase metastasis is when cancer cells escape their original site a tissue lining your stomach would be an _____ tissue epithelial Many layers of cells, with rounded cells at the apical surface, found lining your urinary bladder, comprises transitional epithelium an exocrine gland that accumulates its secretion in a cell's cytoplasm, with the cell bursting to release the secretion, is a holocrine gland cells that make and maintain cartilage arise from chondroblasts In tissue repair, new blood vessels develop from the.... stroma When the gastrula is formed, the developing human is called a(n) ______. zygote the formation of the mesoderm germ layer occurs at gastrulation the embryonic trophoblast is responsible for forming the embryonic contributions to placental tissue which layer of the epidermis has cells flattening as their organelles deteriorate and the cells begin to die? this layer provides waterproofing to your skin stratum granulosum which type of glands produce perspiration in your axillary area, sometimes in response to stress apocrine glands the hair of your eyebrow is terminal epidermis is derived from ectoderm which type of hair follicle grows only for a short time terminal Dora has acute granulocytic leukemia, cancer of her white blood cells. Normally, these cells fight infection. Would you expect Dora to be more or less prone to infection now that she has leukemia? Why? more prone to infection; those cancerous cells don't function normally which would you expect to find lining your small intestine to aid in absorption of nutrients microvili pathological anatomy refers to study of anatomical changes occurring with disease histology refers to study of tissues Which best summarizes the relationship of anatomy to physiology? form follows function which one is a role of the nervous system responds to stimuli by activating glands The anatomical position is characterized by all of the following except ________. palms turned posteriorly
