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.
1 The Trendelenburg position uses gravity to assist in the filling and distension of the upper central veins when placing a central line in the internal jugular or subclavian veins. 2  It is also used in the placement of an external jugular peripheral line for the same reason. The Trendelenburg position is also used when placing a central venous line. 2  The Trendelenburg position uses gravity to assist in the filling and distension of the upper central veins when placing a central line in the internal jugular or subclavian veins.
