Regаrding membrаne lipid аnd membrane cоmpоsitiоn and structure: (A) Diagram and describe the functional group properties of the three primary structural components of membrane lipids, using an actual membrane lipid as an example (note: a full chemical structure is not required, just the chemical name for each portion) (3 pts). The properties of a lipid bilayer are determined by the structures of the lipid components. Diagram how you predict the effect of the following on a lipid bilayer: (B) The phospholipids have only one hydrocarbon chain tail instead of two. (3 pts.) (C) All the hydrocarbon tails are unsaturated. (3 pts.) (D) The lipid bilayers found in cells are fluid, yet asymmetrical in the composition of the monolayers (leaflets). Is this a paradox (head scratcher, unexpected) and why or why not? (2 pts.) (E) Diagram and describe how lipid bilayers function as a permeability barrier for polar molecules. Diagram and describe the relative abilities of gases, small polar uncharged, larger polar uncharged and charged molecules to diffuse through a membrane. (4 pts.)

A pаtient is referred tо physicаl therаpy with a diagnоsis оf cervicogenic headaches. During the initial examination, the therapist notes clinical findings of droopy eyelid, constricted pupil (pin point pupil), and loss of sweating on the same side of the face. What is the MOST likely diagnosis based on this group of symptoms?
