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

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

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...

Pilocytic Astrocytoma

http://www.gliomas.info/pilocyticastrocytoma.htm

Pilocytic Astrocytomas of the Optic Nerve, Hypothalamus, and Cerebellum. Optic Nerve Pilocytic Astrocytoma (Optic Nerve Glioma). Although the neoplastic cells in the lesions are astrocytic in morphology, their cell of origin is unknown, because similar cells are not recognized components of the normal nerve. The normal fibrillary astrocytes of the optic nerve produce only rare neoplasms. These occur predominantly in adults and are similar in their invasiveness and aggressiveness to the fibrillary...The t...

For more details please refer to:. In common with their cell of origin, ependymomas are found throughout the central nervous system, from frontal horns to filum terminale. Intracranially, most occur in the fourth ventricle of children, although supratentorial neoplasms appear in both children. And adults. The spinal lesions, especially those of the filum terminale, are usually seen in adults. A rare neoplasm arises as a primary tumor in sacral soft tissues or bone. In such fibrillar areas, as well as in ...
