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. Also known as Babinski's sign. [Joseph F. Babinski (1857- 19321, French neurologist].
Babinski sign is reflex dorsiflexion of the great toes and fanning of the other toes by stroking the lateral side of the sole of the foot. This stroke is often continued across the ball of the foot toward the base of the great toe. This occurs in patients with upper motor neuron damage.
