SKELETAL MUSCLE CONTRACTION AND THE MOTOR UNIT

http://www.neurohistopathology.com/motorunit.htm

SKELETAL MUSCLE CONTRACTION AND THE MOTOR UNIT. SKELETAL MUSCLE CONTRACTION AND THE MOTOR UNIT. Researchers have learned that muscle contraction cannot proceed in the absence of adenosine triphosphate (ATP) and Ca. A single skeletal muscle is composed of many thousands to millions of long, narrow contractile cells called muscle fibers (Fig-1). These fibers are clustered together in parallel bundles called fasciculi. Each muscle fiber is 10 to 80 µ. That are activated during muscle contraction. During con...

MUSCLE TONE - SPINAL REFELXES

MUSCLE TONE - SPINAL REFELXES. MUSCLE TONE - SPINAL REFELXES. OVERVIEW OF MUSCLE TONE. The muscle tone exhibited by otherwise relaxed muscles is necessary for these muscles to produce effective movements. If muscles relaxed completely (no resting tone), they would overlengthen, and too much time would be required to take up slack when a contraction was called for. On the other hand, too much tone would not allow for sufficient rest and recovery. Innervation of the Spindles. The Myotatic (Stretch) Reflex.

SENSORY PATHWAYS

http://www.neurohistopathology.com/sensorypathways.htm

Ensory pathways include only those routes which conduct information to the conscious cortex of the brain. However, we will use the term in its more loosely and commonly applied context to include input from all receptors, whether their signals reach the conscious level or not. GENERAL SOMATIC AFFERENT (GSA) PATHWAYS FROM THE BODY. Fast and Slow Pain. Discriminating (Epicritic) Touch, Pressure, and Kinesthesia. Some of the subconscious proprioceptive input from the cervical region follows an alternate rou...
