Cells are specialised to do different jobs. They are usually arranged into tissues. A tissue contains many cells all of the same kind and all doing the same jobs. You must know about a variety of animal cells for your GCSE exam, so here are some examples. This is a fairly typical animal cell. Like all other animal cells it has a nucleus, cytoplasm and a cell membrane.
Trendelenburg Gait. A positive Trendelenburg gait (gluteus medius gait/lurching gait) is generally indicative of hip abductor weakness. The classic Trendelenburg's gait pattern is seen when the stance phase hip abductors cannot resist the pull of gravity on the unsupported swing phase lower extremity.The therapist will observe the swing phase pelvis dip below level.reatment of Trendelenburg gait is by strengthening of the abductor muscles when possible. Treatment of the lurching gait pattern is by strongly encouraging patients to use forearm crutches, which will decrease both the energy of walking and the force on the joints in the lower extremities, especially the knee joint.
three-point gait that in which both crutches and the affected leg are advanced together and then the normal leg is moved forward. See illustration at crutches. two-point gait that in which the right foot and left crutch or cane are advanced together, and then the left foot and right crutch.See illustration at crutches.addling gait exaggerated alternation of lateral trunk movements with an exaggerated elevation of the hip, suggesting the gait of a duck; characteristic of muscular dystrophy.
