Advanced Anatomy Unit 1 Exam Flashcards
Anatomy
study of the structure of body parts and their relationships to one another
Cytology
study of the cells of the body
Histology
study of the tissues of the body
Developmental anatomy
study of the structural changes which occur from conception to old age
Embryology
study of developmental changes during the first eight weeks of development
6 levels of organization
chemical, cell, tissue, organ, organ system, organism
Types of tissue
epithelial tissue, connective tissue, muscle tissue, nervous tissue
Abdominal regions
right hypochondriac, epigastric, left hypochondriac, right lumbar, umbilical, left lumbar, right iliac, hypogastric, left iliac
Serous membranes
covers organs and cavities of the trunk; composed of connective tissue and simple squamous epithelial tissue
Plasma membrane
forms outer cell boundary and separates the internal environment from the external
Cytoplasm
contains cytosol, cytoskeleton, inclusions, and organelles; site where most cell activity takes place
Nucleus
control center containing DNA
Central dogma
DNA transcripting to RNA, RNA transcribing to proteins
Plasma membrane lipids
phospholipids and cholesterol
Marker molecules
involved in cell to cell recognition (mostly glycoproteins or glycolipids)
Attachment proteins
attach cells to other cells, extracellular molecules, or intracellular molecules
Channel proteins
involved with transportation of substances in and out of a cell
Receptor proteins
contain binding sites that bind to specific substances
Carrier proteins
move substances from one side of the PM to the other
Cytosol
fluid portion of the cytoplasm
Cytoskeleton
provides support and structure and is involved in the movement of cellular structures
Ribosomes
sites of protein synthesis, there are both fixed and free ribosomes
RER
has ribosomes on the outer surface and produces proteins
SER
functional in lipid synthesis, storage of Ca ions in muscle cells, and detoxification
Golgi apparatus
pimp and ride; modifies and packages proteins produced by the RER and lipids produced by the SER
Lysosomes
contain acidic enzymes; abundant in phagocytes; rupture results in self digestion of the cell (autolysis)
Mitochondria
produces ATP
Motile celia
extensions of the plasma membrane that move materials over the cell (fallopian tubes, trachea, bronchi)
Primary celia
involved in sensation (rods, olfactory neurons)
Microvilli
finger-like projections from the PM; increase surface area; found in cells that undergo absorption
Epithelial tissue functions
covers body surfaces, lines hollow cavities, organs, and ducts, and forms glands
Connective tissue functions
protects and supports the body and its organs, binds organs together, stores energy reserves as fat, and provides immunity
Muscle tissue functions
movement and generation of force
Nervous tissue functions
initiates and transmits action potentials, coordinating bodily functions
Primary germ layers within the embryo
endoderm, mesoderm, ectoderm
Tissue derivations
Epithelium from all three germ layers, connective and muscle tissue from the mesoderm, nerve tissue from ectoderm
