List, define, and identify roles for muscle tissue ANS - 3 types: skeletal, cardiac, smooth
- all are specialized to generate mechanical force
- skeletal: attached through other structures to bones to produce movements; attached to skin (e.g., for facial
movements); voluntary
- cardiac: found only in the heart; cause heart to contract and pump blood; involuntary
- smooth: make up walls of many tubes in the body (e.g., blood vessels, GI tract); involuntary
List, define, and identify roles for nervous tissue ANS - neuron: initiate, integrate, and conduct electrical
signals to other cells, sometimes over long distances
- major means of controlling activities of other cells
- brain and spinal cord are nervous tissue
List, define, and identify roles for epithelial tissue ANS - epithelial cell: selective secretion and absorption
of ions and organic molecules
- cuboidal, columnar, squamous, ciliated
- may be single-cell-thick (simple epithelium) or many layers (stratified epithelium)
- epithelial lining airway = ciliated
- line inside of organs and tubular and hollow structures
- these cells rest on the basement membrane (basolateral = side of cell anchored to basement membrane; apical
= faces interior of a structure)
- cells are held together by tight junctions - regulate selective exchange of molecules
List, define, and identify roles for connective tissue ANS - connect, anchor, and support the structures of
the body
- loose (underlying most epithelial layers) and dense (tendons and ligaments)
- bone, cartilage, and adipose tissue
- blood - delivery of nutrients, removal of waste, transport of chemical signals
- ECM
, ECM ANS - mixture of proteins, polysaccharides, minerals
- 2 general functions: scaffold for cellular attachments and transmits info in the form of chemical messengers
to help regulate activity, migration, growth, and differentiation
- some proteins of ECM are known as fibers, insol. proteins including ropelike collagen fibers and rubberband-
like elastin fibers
- links in communication between extracellular messenger molecules and cells
circulatory system ANS (aka cardiovascular system) This system works as the transportation highway for
the body. It consists of the heart, blood, and blood vessels. It transports substances such as oxygen, carbon
dioxide, and nutrients in the body.
digestive system ANS Digestion and absorption of nutrients and water. elimination of wastes.
endocrine system ANS the body's "slow" chemical communication system; a set of glands that secrete
hormones into the bloodstream; regulation and coordination of many activities in the body, including growth,
metabolism, reproduction, BP, water, and electrolyte balance
immune system ANS A system (including the thymus and bone marrow and lymphoid tissues) that protects
the body from foreign substances and pathogenic organisms by producing the immune response
integumentary system ANS protection against injury and dehydration; defense against pathogens;
regulation of body temp
lymphatic system ANS collection of extracellular fluid for return to blood; participation in immune
defenses; absorption of fats from digestive system
musculoskeletal system ANS the system of bones and skeletal muscles that support and protect the body
and permit movement; production of blood cells
nervous system ANS regulation and coordination of many activities in the body; detection of and response
to changes in the internal and external environments; states of consciousness; learning; memory; emotions
reproductive system ANS male: production of sperm, transfer of sperm to female
