Bone Tissue
What are the two types of bone marrow and name their functions?
Red marrow= bone cell prod
Yellow marrow= adipose/energy storage
What is the definition of an articulation?
Place where two bones come together to form a joint
Most common type of arthritis; wear and tear
Osteoarthritis
Contractile unit of the muscle cell
Sarcomere
Aerobic respiration
Which structure would you observe on an x-ray to determine if a bone was still growing?
Epiphyseal plate
Diarthrosis
Excessive production of growth hormone may lead to this...
Acromegaly or Gigantism
Contains troponin and tropomyosin
Actin
Muscle contraction with increased tension without change in muscle lenght
Isometric
This component of bone matrix gives bone its strength.
Hyaline- synchondrosis
Fibrocartilage- symphsis
Autoimmune condition of the nervous system that results in destruction of the myelin sheath leading to muscle weakness and possible paralysis
Multiple sclerosis
Storage and release of Ca++
Sarcoplasmic reticulum
Abnormal lateral curve of the spine
Scoliosis
Name the four primary cells found in bone tissue.
Osteoprogenitor/osteogenic cell
Osteoblast
Osteocyte
Osteoclast
Name a characteristic of a synovial joint
Joint capsule, articular cartilage, synovial fluid, disc, meniscus, bursa, ligaments, tendons, highly moveable, appendicular skeleton
Sustained muscle contraction after death due to lack of ATP to detach myosin head and actin
Rigor mortis
The type of nerve and neurotransmitter found at the neuromuscular junction
Somatic motor neuron- neuromuscular junction
Type of muscle fiber found in endurance athletes (marathon runners)
Slow twitch fibers (Type I)
Stress stimulates osteoblasts to lay down matrix, thus making bone stronger
The elbow joint is an example of this type of synovial joint classification
Inflammatory, autoimmune arthritis that deteriorates the joint capsules; causes pain, redness
Rheumatoid arthritis
what immediately occurs following binding of ACh to receptors on the motor end plate of the sarcolemma
Sodium channels open--> depolarization of the sarcolemma--> action potential through the muscle fiber
Hormone responsible for raising low blood calcium levels by stimulating osteoclasts to break down bone and release calcium into the blood
Parathyroid hormone
