PENGENDALIAN GERAKAN MOTORIK SOMATIKS. Amin Singgih

Pelaksanaan Gerakan TubuhMemerlukan beragam kelompok otot yang dikoordinasi kegiatannya, baik pengaktifan maupun inhibisinyaSetiap gerakan menggunakan seperangkat kelompok otot yang berbeda, untuk menghasilkan gerakan dengan ARAH - KECEPATAN KEKUATAN tertentu

Konsep dasar pengendalian motorik di tingkat medulla spinalisDi medulla spinalis terdapat rangkaian neuron untuk pelaksanaan gerakan secara refleks maupun untuk gerakan tubuh yang dikehendakiInteraksi antar neuron dalam medulla spinalis mengkoordinasi beragam kelompok otot secara sinergis maupun antagonis untuk menghasilkan gerakan volunter atau gerakan secara refleks yang dibangkitkan oleh reseptor sensorik
