Question | Answer |
cells (cyte-) | basic unit of structure; a living factory |
cell membrane | semipermeable boundary that serves as a doorway to the cell |
nucleus | control center that contains chromosomes (23 pair: 22 body 1 sex), genes, RNA, and DNA |
cytoplasm | cell substance that contains organelles (little organs) |
(cytoplasm)Mitochondria | cell "batteries" that store energy |
(cytoplasm)Lysosomes(some: body; lyso: dissolve) | carry out digestive functions of the cell |
(cytoplasm)Golgo apparatus | makes secretions |
(cytoplasm)Endoplamic reticulum | transport system and protien synthesis |
(cytoplasm)Cilia (flagella) | hairlike extensions responsible for motility (movement of the cell itself or fluid around the cell) |
Transport across the cell membrane DIFFUSION (spreading out) | molecules moving to a less concentrated area, as oxygen moving from aveoli in the lungs into capillaries |
Transport across the cell membrane OSMOSIS | DIFFUSION OF WATER MOLECULESACROSS A SEMIPERMEABLE MEMBRANE TO A CONCENTRATED AREA FOR THE PURPOSE OF DILUTION |
Transport across the cell membrane FILTRATION | movement of molecules through a filter or a semipermeable membrane as a result of pressure |
Transport across the cell membrane ACTIVE TRANSPORT | use of energy to move molecules across a membrane to a higher concentration |
some cells are also capable of | phagocytosis (cell eating) and pinocytosis (cell drinking) as in the case of white blood cells engulphingbacteria and proximal kidney tubules reabsorbing filtered protiens |
Cell Division | some cells, such as RBC and nerve cells do not divide or reproduce |
Body tissues | collection of specialized cells designed for a special function |
epithelial tissue | lines (cavities and vessel, covers (body and organs), and secretes (glandular) |
epithelial cells are named by their shape | squamous (simple squamous and stratified squamous), cubodial, columnar |
simple squamous | covers surface of pleura, peritoneum, and pericardium and lines the blood vessels |
stratified squamous | skin, lines mouth and esophagus |
cubodial (epithelial tissue | lines the surface of kidney, tubules and covers ovaries |
columnar | lines the stomach, intestines, and part of the respiratory tract |
Body tissue may be | ciliated (contain hairlike cilia designed to move fluid) or non-ciliated |
Body tissue | regenerates readily and heals quickly |
Body tissue is | innervated and capable of sensations |
In surgery body tissue | is generally sutured with absorbable sutures (exception the skin) |
cancer of the epithelial tissue is | carcinoma (basal cell or squamous cell) |
two types of body tissue membranes | mucous membranes and serous membranes |
Mocous Membranes | lines cavities leading to outside, such as GI tract, GU tract, and respiratory tract |
Serous Membranes | lines enclosed cavities such as the peritoneum (lines abdomen), pericardium (sac that encloses heart) and pleura (lines chest) |
Connective Tissue | most variable and widespread tissue in the body |
connective tissue has three functions | Binds, Protects and Supports |
6 types of connective tissue | 1. Adipose (fat), 2. Fibrous (fascia), 3. Cartilage (chondra), 4. Bone (osseous tissue)5. Reticular (netlike), 6. Areolar |
Adipose Tissue (fat) | connective tissue that has a poor blood supply and is generally sutured with absorbable materials |
Fibrous Tissue (fascia) | tough connective tissue - composes sheaths, covering joints, muscles, meninges (coverings of the brain and spinal cord), synovium (lining of the synovial joints), scar tissue, tendons, and ligaments |
Cartilage (chondra) | elastic tissue (gristle) that has little blood supply |
Bone | corticle (compact)and cancellous (spongy |
Corticle bone (compact) | bone cells arranged in concentric circles around central (haversion) canals; make up shell of bone to provide strength and support and covered by periosteum |
Cancellous Bone (spongy) | bone contains spaces with red marrow for making blood cells |
reticular (net like) | blood and lymph tissue |
areolar | loose connective tissue that fills spaces and helps to hold organs in place |
3 types of muscle tissue | 1. skeletal, 2. smooth, 3. cardiac |
skeletal muscle | striated, voluntary |
smooth muscle | visceral (found in such organs as blood vessels and bladder), involuntary |
cardiac muscle | striated, involuntary |
nerve tissue | most highly specialized tissue |
nerve tissue is found in | nerves, brain and spinal cord |
neurons(nerve cells) | basic unit of structure in the nervous system; made up of dendrites, cell body, and axon |
dendrites | cell extensions that receive nerve impulses |
axon | extension of the cell that conducts impulses away from the cell body) |
neuroglia (schwann cells) | non conductive covering of peripheral nerves which provide nutrition and protection, make up the myelin sheath for the neurons and gives nerves a white glistening appearance |
nerve tissue coordinates and integrates | BODY FUNCTION |
Body organs | composed of different types of tissues and perform specific functions (liver, heart) |
Body System | composed of different organs working together to perform specific functions |
