What else can I help you with?
What Consists of all outgoing motor pathways?
The corticospinal tract, extrapyramidal system, and rubrospinal tract together form the major outgoing motor pathways from the brain to the body. These pathways control voluntary movement and posture by transmitting motor signals from the brain to the spinal cord and ultimately to the muscles.
What are the subdivisions of pyramidal tracts?
Vestibulspinal tract (majority of its fibres are uncrossed)Olivospinal tractMedial Reticulospinal tract*mnemonic to memorize: V-O-MER
What spinal tract might be damaged if lack of voluntary movement is observed?
lateral corticospinal tract -this would be the most major one anterior corticospinal tract - to a lesser extent a lesion of the rubrospinal tract would affect voluntary movement but not cause a lack of it
What is of epithelial origin?
Skin, hair, nails, and the lining of organs such as the respiratory tract, gastrointestinal tract, and urinary tract are of epithelial origin. Epithelial cells serve as a protective barrier and have various functions depending on their location in the body.
The descending pathway from the red nucleus to the lower motor neurons is the Tract?
The descending pathway from the red nucleus to the lower motor neurons is known as the rubrospinal tract. This tract plays a role in the coordination of movement and the regulation of muscle tone, particularly in the upper limbs. It originates in the red nucleus of the midbrain and descends to influence motor neurons in the spinal cord, primarily facilitating flexor muscle activity.
A lateral tract in the spinal cord would be?
Rubrospinal
What are the extra-pyramidal tracts that cross to the opposite site of spinal cord?
Rubrospinal tractTectospinal tractLateral reticulospinal tract

What type of muscle is responsible for the movement of the arms and legs?
It is the Rubrospinal Tract. It's main role is the mediation of voluntary movement. It is responsible for large muscle moments such as the arms and legs as well as fine muscle movement.

What is the origin of tectospinal tract?
It arises from superior colliculus of midbrain.
What is Benedict's syndrome?
complete or partial oculomotor nerve palsy; and contralateral tremor (due to damage of rubrospinal tracts.)
What are the sites of origin of the pyramidal tract?
the pyramidal cells in layer 5 of areas 4, 6 ,3-1&2
What's Tuberculosis?
TB is caused by infection with the bacterium Mycobacterium tuberculosis Sinusitis is a symptom which manifests usually with upper respiratory tract infections.Common cold is a upper respiratory tract infection of viral origin, usually caused by rhinovirus
