Phospholipids are the essential 'bulk' part of the lipid bilayer that make up cell membranes. Phospholipids have a hydrophylic (water-loving) phosphate head and hydrophobic (w â¦ ater-hating) aliphatic hydrocarbon tails. lipid bilayer is a double layer membrane formed from phospholipids. Phospholipids are composed of a polar head group and non-polar fatty acid tails. The arrangement of the p â¦ hospholipids makes the cell membrane permeable. 4 people found this useful.
the innate reflex occurring in a healthy infant whereby the toes extend upward when the sole of the foot is gently stimulated.This response generally disappears by the time the baby walks, but it may reappear in adults if there is a loss in the function of the upper motor neurons.

Babinski (1857- 19321, French neurologist].his response generally disappears by the time the baby walks, but it may reappear in adults if there is a loss in the function of the upper motor neurons.

1 The abnormal plantar reflex, or Babinski reflex, is the elicitation of toe extension from the wrong receptive field, that is, the sole of the foot. 2  Thus a noxious stimulus to the sole of the foot produces extension of the great toe instead of the normal flexion response. The plantar reflex is a nociceptive segmental spinal reflex that serves the purpose of protecting the sole of the foot. 2  The clinical significance lies in the fact that the abnormal response reliably indicates metabolic or structural abnormality in the corticospinal system upstream from the segmental reflex.
