BIOS 252 Midterm Review Definitions: 1. Origin: the attachment of a muscle’s tendon to the stationary bone. 2. Insertion: the attachment of the muscle’s other tendon to the moveable bone 3. Sarcomere: the basic functional units of myofibril. It extends from one Z disc to the next Z disc. 4. Sarcolemma: the plasma membrane of a muscle cell. Where transverse tubules (t-tubule) are attached to it and go to the sarcoplasmic reticulum. 5. A band: darker middle part of the sarcomere. 6. I ...

Week 2 Nervous System-Introduction Learning Outcomes: ●Organize the NS into structural and functional divisions ●Locate and identify the cellular components of nervous tissue ●Explain the formation of the resting membrane potential and the action potential, and the propagation of the action potential to form a nerve impulse. ●Explain the factors involved in the transmission of an action potential from one neuron to another in the synapse. Introduction The nervous system is a vas...

What Cellular Structure Is Degenerating & Rebuilding in MS? Multiple sclerosis (MS) is caused by the degradation of oligodendrocytes by the cells of the immune system that create the myelin sheath protecting the axons of neurons in the central nervous system (Smith, 2019). With the degeneration of the myelin sheath, the nerve conduction hampers highly which ultimately develops symptoms like tiredness, vision problems, numbness and tingling, stiffness and fatigue, muscle spasms, problems of ve...

What cellular structure is degenerating and rebuilding in MS? In multiple sclerosis, the oligodendrocytes and myelin sheaths of the CNS deteriorate and are replaced by hardened scar tissue. (Saladin, 2021) 2. Does this explain the progression we see with the signs and symptoms? Explain why. Yes, when the o...
