A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity. Mitosis involves the division of the nuclear contents and the distribution of identical sets of chromosomes to the new cells; cytoplasmic division (cytokinesis) involves the division of the cytoplasm and cytoplasmic organelles. Synovial joints are characterized by the presence of a joint cavity. They should use a different color for each of the individual bones in the series. Structural and functional differences distinguish synovial joints from cartilaginous joints (synchondroses and symphyses) and fibrous joints (sutures, gomphoses, and syndesmoses).
This type of tissue contains only short, thin, collagenous fibers (reticular fibers) that are widely scattered. Tibialis anterior Extensor digitorum longus Fibularis (peroneus) brevis.

The purpose provides a statement concerning the intent of the exercise—that is, what will be accomplished. Answers will vary, however many students will conclude that the data will support the original hypothesis. Microtubules pull chromosomes toward centrioles. Mitochondrion (cross section) 5.
Movement is medicine for joints. The laboratory exercises include a variety of special features that are designed to stimulate student interest in the subject matter, to involve students in the learning process, and to guide them through the planned experiences.

This will cause pain, swelling, or tenderness of the bursa and surrounding area, and may also result in joint stiffness. The parts, which are always built in advance of the surgery, are sometimes custom made to produce the best possible fit for a patient. Lateral rectus Inferior rectus Inferior oblique. They need to be reminded to perform all tests, as students often think if they get one positive result they can stop. 8. f i c d. PART A (molecules and bonding) 1.
