WebGolgi tendon organs (GTOs) are proprioceptors that are located in the tendon adjacent to the myotendinous junction . The Golgi tendon organ is a tree-like sensory ending enclosed in a spindle-like connective tissue capsule, that lies near the junction of a tendon with a muscle. In man, some 10 to 20 muscle fibres are connected to one tendon organ. Web17 Nov 2015 · The mitotic spindle apparatus serves to pull duplicated chromosomes apart. When a dividing somatic cell has duplicated its DNA it can proceed to mitosis. During …

WebThey are absolutely required for correct positioning and orientation of the mitotic spindle apparatus, and are thus involved in determining the cell division site based on the geometry and polarity of the cells. The maintenance of astral microtubules is dependent on centrosomal integrity.
WebRal family is a member of Ras-like GTPase superfamily, which includes RalA and RalB. RalA/B play important roles in many cell biological functions, including cytoskeleton dynamics, cell division, membrane transport, gene expression and signal transduction.
