| Question | Answer |
|---|---|
| Where is striated msucle tissue found? | Boney Skeleon |
| Striated muscle is voluntary or involuntary? | voluntary muscle |
| Striated muscle can contract to.. | 1/2 of it's orginal size |
| Smooth muscle is found where? | Viscera (guts) organs, and Cardiovascular systems vessels |
| Smooth muscles is voluntary or involuntary | Involuntary |
| Smooth muscle is striated or non-striated | non-striated |
| Cardiac Muscle is found where? | Walls of the heart |
| Cardiac muscle is voluntary or involuntary? | Involuntary |
| Cardiac looks like? | Striated |
| Compact | Dense outer layer -- hard |
| Periosteum | outer covering of compact bone |
| Marrow | Spongy inside of bones |
| How many bones are in the human skeleton? | 206 |
| Axial skull contains | hyoid bone, rib cage, vertebral column |
| Appendicular-pectoral girdle contains | clavical, scapula, upper extermities, pelvic girdle. and lower extermities |
| Matrix | Substance inside the bone that is mmixed with minerals (salts). It makes the bones hard |
| Synarthrodial | Immoviable |
| Amphierthrodial | Yeilding |
| Diarthrodial | Freely moving |
| Fibrous | EX. Cranial sutures |
| Cartilaginous | Ex. Vertebral column |
| Synovial Fluid | Protects the joint from impact and friction, Provides nourishment, lubricates the joint. |
| Nervous tissue is made up of | Nerve cells --neurons |
| Neurons are comprised of | Cell Body, Dendrites, Axon, Terminal |
| Glial | acts as support cells of NS, Form myelin on the axons of neurons, |
| Dendrites | Recieve electrical signals and conduct those signals toward the cell body |
| Cell body | Houses the nucleus and a number of organelles critical to the function of the nuron |
| Axon | projects off the cell body and transmits the electrical signal down the axon in one direction toward the terminal |
| Terminal | Is adequately stimulated releases a chemical to carry the message to the next nearon in line |
| Impulse | When the axon transmits information |
| Synapse | Interactiong between the terminal and another neuron or muscle |
| Myelin | Insulation covering found on axons, made of glial cells, significant to transmit signals rapidly |
| Neurotransmitters | Chemical released by terminal. |
| Why are neurotransmitters needed? | For contraction of the muscle to take place |
| Neuromuschular synapse | Synapse between motor neurons and the muscles |
| Motor unit | A given motor neuron and all the muscle fibers it intervates |
| CNS | Brain and spinal cord |
| PNS | Visceral and somatic |
| Visceral can futher be divided into | motor and sensory |
| Visceral motor can be divided into | sympathic and parasympathic |
| Somatic can be divided into | motor and sensory |
