Histology - - Answethe study of tissues
Mitosis and Meiosis - - AnsweMitosis and meiosis are the ways that cells reproduce. During mitosis, a
cell duplicates its DNA and divides into two identical cells called daughter cells. Meiosis, on the other
hand, produces four daughter cells that have only half of the chromosomes that the parent cell has.
Meiosis is the form of cell duplication that produces eggs and sperm.
Skin - - Answermembrane because it covers the body ; organ because it contains several kinds of tissues.
skeletal system – - Answe Functions to support, permit movement, form blood cells (homeopoiesis),
protect internal organs, detoxify, point for muscle attachment, mineral storage (particularly
phosphorous and calcium)
Muscular System - - AnsweConsists of skeletal muscles and tendons that connect muscles to bone, and
ligaments which attach bones to each other to form joints. Cardiac and smooth muscles are not included
in this organ system.
Nervous System - - AnsweComposed of neurons (cell, axon, dendrite), central nervous system (brain,
spinal cord), peripheral nervous system (nerves of the body). Recieves, interpretes and transmits
impulses and responses. Responsible for sight, smell, taste, touch, hearing (five senses), heart rate,
breathing, speech, movement
Endocrine system - - AnsweConsists of a group of ductless glands that secrete substances called
hormones directly into the bloodstream. Hormones are powerful chemical substances that have a
,profound effect on many body processes such as metabolism, growth and development, reproduction,
personality, and the ability of the body to react to stress and disease.
Circulatory system - - AnsweThe human body system that contains the heart, blood, and all of the blood
vessels. It delivers all the nutrients to the cells
Respiratory System - - AnsweA system of organs, functioning in the process of gas exchange between
the body and the environment, consisting especially of the nose, nasal passages, nasopharynx, larynx,
trachea, bronchi, and lungs.
Digestive System - - Answe3 main functions - break down food mechanically & chemically, absorb
important molcules for the body needs, & eliminates wastes
Urinary System - - AnsweComposed of kidneys, ureters, bladder, and urethra. Removes waster material
(urine) from the body, regulates fluid volume, and maintains electrolyte concentration.
Reproductive system - - Answe(testes, epididymis, vas deferens, urethra, penis, ovaries, Fallopian tubes,
uterus, vagina) produces reproductive cells, nurtures and protects developing embryo in females
Alimentary Canal - - AnsweAlso known as the gastrointestinal (GI) tract of the digestive tract, the
alimentary canal is the long muscular "tube" that includes the mouth esophagus, stomach, small
intestine, and large intestine.
anatomic position - - AnsweThe position with the body erect with the arms at the sides and the palms
forward. The anatomic position is of importance in anatomy because it is the position of reference for
anatomic nomenclature. Anatomic terms such as anterior and posterior, medial and lateral, and
abduction and adduction apply to the body when it is in the anatomic position.
Anterior - - AnsweFront or Ventral
appendicular skeleton - - Answe126 bones that make up the shoulder girdle, arms, hands, pelvic girdle,
legs, and hands.
, arterioles - - AnsweExtremely small arteries that result from multiple branching of major arteries.
Function to direct and control blood flow and to reduce blood pressure
Axial Skelton - - Answerts the central axis of the body. Consists of the sku
bolus - - AnsweA term used to describe food after it has been chewed and mixed with saliva.food is
swallowed and passed from the esophagus into the stomach, where digestion continues with the mixing
of chyme with hydrochloric acid, enzyme action, and intrinsic factor.
Cell - - AnsweCollection of living matter enclosed by a barrier that separates the cell from its
surroundings; basic unit of all forms of life.
Cerebellum - - AnsweBALANCE, physical, emotional, cognitive, social;the "little brain" attached to the
rear of the brainstem; its functions include processing sensory input and coordinating movement output
and balance
Chyme - - AnsweA pulpy mixture of food and gastric juices. Produced in the stomach, from which it
passes to the small intestine
Dermis - - Answe- the layer of the skin just below the epidermis, contains bundles of collogen, nerve
fibres, blood vessels, sweat glands, sebaceous glands & hair follicles
Distal - - Answeopposite of proximal; a particular body part is farther from the trunk or farther from
another specified point of reference than another part
Epidermis - - AnsweKeratinized stratified squamous epithelium containing 4 distinct types of cells,
melanocytes(pigment)merkel cells(touch receptors)ketatinocytes(produce keratin) and langerhans
cells(police outer body surface/immune response cells) and either 4 or 5 layers depending on whether
thin(everywhere on body except) or thick(soles and palms) skin. Avasulcar but innervated, reproduces
quickly -entirely new epidermis every 35-45 days.
Estrogen - - AnsweWhat hormone stimulates uterine growth, increases blood flow to uterine vessels,
and stimulates breast ducts to prepare for lactation?
