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].
The patient is usually asked to undress, so the neurologist can see the muscles and look for atrophy (shrinkage), twitching, or abnormal movements. Tests are done to evaluate strength in all the major muscle groups. Evaluating Babinski response is an important part of testing the motor system. The neurologist strokes or scratches, heel-to-toe, the outer side of the sole of the foot and in patients over the age of 2, the toes normally curl downward in response. If the toes fan upward, a brain or spinal cord injury is indicated.
