Okinawan Seito Matsumura Shorin-ryu is an old village style of karate taught as a highly aesthetic art form steeped in cultural tradition and extremely effective for personal protection. Shuri-ryu is a stylized sport form of karate that is very athletic and competition oriented. This dual approach to presenting karate results in a well rounded program which offers the best in fitness, self-defense, sport, authentic tradition, and fun.
How Elbow joint essay Write a Summary of an Article? A study of anatomy and physiology of movement of upper limb The procedure in lifting the hand to drink water is a complex one which involves a huge amount of technology inter-transfer between the brain and the eventual skeletal muscle.
The primary motor area is located at the precentral gyrus of the frontal lobe. Within this area lies the cell body of the primary neuron. These neurons are known as upper motor neurons UMN. These UMNs receive modulating impulse from the inputs from the cerebellum and the basal ganglia via the extrapyramidal pathways.
These tracts modulate the gross movement initiated at the frontal cortex. In turn these areas are modulated by afferent signals from ascending spino cerebellar, and spino-thalamic pathways. The signal initiated at the nucleus of the cell body is transmitted electronically via the axon of the myelinated neuron via the mode of salutatory conduction.
The myelin sheath which surrounds the axon of nerves that involve fast transport, breaks at intermediate regions known as Nodes of Ranvier. Like all excitable tissue, nerves maintain a resting membrane potential that is the difference of voltage across the membrane of the neuron.
This impulse generated at the axon hillock is transmitted via the depolarizing phase which allows sodium ions ingress into cells via opening of the Na channels.
This entry of Na in one portion allows activation of other Na channels, causing depolarization of the adjacent region of the neuron.
Subsequently repolarization occurs via the opening of K channels, which restores the membrane potential. Thus this process continues which allows the transmission of impulse.
It is the former which is responsible for the upper limb movements. The cortico-spinal tract travels in the anterior horn cell of the spinal cord till the brachial plexus where they synapse with the spinal ventral root neuron lower motor neuron. A single post-synaptic neuron receives signals from many neurons.
At the axon terminal, the propagation of impulses leads to release of neurotransmitters, which are stored in specialized vesicles.
The released Ach diffuses into the synaptic cleft and binds with receptors on the post synaptic membrane to produce excitatory post synaptic potentials. This leads to generation and propagation of impulse in nerves which are destined to innervate the neuro-muscular junction.
At the neuro-muscular junction, Ach is released, which diffuses into the synovial cleft and binds to receptors in the motor end plate, and triggers a muscle action potential.
The released Ach is destroyed by the acetylcholinestrase. At the level of the sarcolemma of the muscles, the muscle AP travels along T-tubules, opening Ca release channels in the sarcoplasmic reticulum.Clinical History: A 28 year-old male complains of shoulder pain after falling while playing ultimate Frisbee.
A (1a) fat-suppressed T2-weighted coronal oblique image through the plane of the acromioclavicular joint and a (1b) fat-suppressed T2-weighted coronal oblique anterior to the plane of the acromioclavicular joint (ACJ) are provided.

The shoulder-joint is an enarthrodial or ball-and-socket joint.
The bones entering into its formation are the hemispherical head of the humerus and the shallow glenoid cavity of the scapula, an arrangement which permits of very considerable movement, while the joint itself is protected against displacement by the tendons which surround it.
