Homeostatic functions of body systems | integumentary lymphatic muscular immune endocrine respiratory skeletal digestive nervous urinary cardiovascular reproductive |
Name the major tissues of the body | epithelial tissue connective tissue muscle tissue nervous tissue |
Name bone cell types and function | osteocytes :mature, inactive bone cell osteoblast: active bone forming cell (bone maker) osteoclast:bone destroying cell(bone breaker) |
Name the layers of the skin | 1 .surface film: 2.epidermis 3. Stratum corneum: Horny layer stratum lucidum: clear layer 4. stratum granulosum granular layer 5 stratum spinosum spiny layer 6.stratum basale base layer 7. dermoepidermal junction :basement membrane 8.derma deep primary layer of the skin 9. papillary layer 10.reticular layer hypodermis (subcutaneous layer) |
Name the bones based on their shape | long bones. flat bones short bones irregular bones. sesamoid bones |
Why would your thyroid release calcitonin? | if your blood calcium level was too high: it slows osteoclasts and tell the osteoblasts to get to work |
Name the parts of the body associated with the axial skeleton | skull, hyoid bone, vertebral column, sternum and ribs |
define bone markings: angle | a corner |
define bone markings : body | the pain portion of a bone |
define bone markings : border | edge of bone |
define bone markings : condyle | rounded bump: usually fits into a fossa on another bone to form a joint |
define bone markings : crest | moderately raised ridge: generally a site for a muscle attachment |
define bone markings : epicondyle | bump near a condyle: often gives the appearance of a "bump on a bump" for muscle attachment |
define bone markings : facet | flat surface that forms a joint with another facet or flat bone |
define bone markings : fissure | long crackle hole for blood vessels and nerves |
define bone markings : forman | round hole for vessels and nerves (pl: foramina) |
define bone markings : fossa | depression: often receives an articulating bone (pl: fossa) |
define bone markings : head | distinct epiphysis on a long bone, separated from the shaft by a narrowed portion (neck) |
define bone markings : line | similar to a crest but not raised as much (is often rather faint) |
define bone markings : margin | edge of a flat bone or flat portion of the edge of a flat area |
define bone markings : meatus | tubelike opening or channelTU |
define bone markings : neck | a narrowed portion, usually at the base of a head |
define bone markings : notch | a v-like depression in the margin or edge of a flat area |
define bone markings : process | a raised area or projection |
define bone markings : ramus | curved portion of a bone, like a ram's horn |
define bone markings : sinus | cavity within a bone |
define bone markings : spine | similar to a crest but raised more: a sharp,pointed process, for muscle attachment |
define bone markings : sulcus | groove or elongated depression |
define bone markings : trochanter | large bump for muscle attachment (larger than a tubercle or tuberosity) |
define bone markings : tuberosity | oblong, raised bump, usually for muscle attachment |
name the primary joint classifications and an example | 1.synarthroses: (immovable) sutures of the skull, between the rib and sternum 2. amphiathroses: (slightly moveable) syndesmosis between the radius and ulna, pubic symphysis 3. diarthroses:(freely movable) shoulder joint |
classification of synovial joints: | UNIAXIAL: around one axis in one place : hinge(elbow joint), pivot(joint between first and second cervical vertebra) BIAXIAL: around two axes perpendicular to each other: saddle (thumb joint) condyloid :(joint between the radius & carpal bones) MULTIAXIAL: around many axes: ball & socket (shoulder & hip joint) gliding:joints between the articular facets of adjacent vertebrae, joints between the carpal and tarsal bones. |
what is a sarcomere? | a contractile unit of muscle cells: length of a myofibril between two Z disks |
