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. Also known as Babinski's sign.[Joseph F. 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.

The examiner begins the stimulation at the heel and goes forward to the base of the toes. Most newborn babies and young infants are not neurologically mature, and they therefore show a Babinski reflex. A Babinski reflex in an older child or an adult is abnormal and is a sign of a problem in the brain or spinal cord.A Babinski reflex that is present on one side but not the other is also abnormal, and it can indicate which side of the brain is involved.he examiner begins the stimulation at the heel and goes forward to the base of the toes.
