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.
This clinical observation is a positive Trendelenburg sign. ischial bursitis. recurrent microtrauma (i.e. from cycling) results in inflammation of the bursa; calcification in the bursa may occur with chronic bursitis. Localized pain occurs over the bursa, and the pain increases with movement of the gluteal maximus.
