Name the four classes of tissues
|
1. Epithelial tissue: flat sheet of tightly interconnected cells. Covers and lines all body pats
2. Connective tissue: individual cells dispersed in a flexible matrix. Holds parts together, provides mechanical support and includes bone and cartilage. 3. Muscle tissue:all muscle cells contract. Comes in three types-skeletal,cardial and smooth 4. Nervous tissue:contains neurons and Glial cells |
|
What is an organ?
|
Two or more tissues that make a distinct structure with a specific function
|
|
True or false, Form follows function
|
True
|
|
Name the three principals of "form follows function"
|
Form may also be thought of as shape/structure of the organism.
Form evolves in response to the demands placed on body part Most form takes shape during an organism's development |
|
Name four ways muscles and skeletons work together
|
1. All animals move by contracting muscles against the skeleton.
|
|
Name three different types of skeletons
|
1. Hydroskeleton: earthworms, fluid-like internal space (coclum)
2. exoskeleton: outside skeleton 3. endoskeleton: inside skeleton |
|
How many muscles does the human body have?
|
600
|
|
Muscles can only exert force in one direction: name that motion
|
Pulling, not pushing
|
|
True or false, muscles move in a tetrigonostic manner?
|
False: the correct answer is antagonstic, meaning "pull in opposite directions"
|
|
Name three kinds of connective tissues
|
1. cartilage: cushions the joint
2. ligaments: attach bones together and around the joint 3. tendons: attach muscle to bone |
|
Name the three major tissue types of the bone
|
1. outer layer: compact bone tissue
2. spongy bone tissue 3. red bone marrow: found inside the spongy bone |
|
Name two ways bones respond to use
|
1. Osteoblasts: specialized cells that make bone
2. Osteoplasts: similar cells that digest collagen and bone matrix |
|
What is osteoporosis?
|
A condition in which the bones become extremely thin and weakened and can easily break due to a loss of bone mineral deposits (decalcification)
|
|
Name the four parts of the vertebrate endoskeleton:
|
1. backbone
2. vertebrae 3. skull 4. sutures |
