Types of Joint Characteristics Position in the body Pivot joint It enables movement in different directions It is the point where the first vertebra joins the skull. Hinge joint It enables movement in one direction alone like a hinge. It is found in fingers, toes, elbows, knees, and ankles Ball and socket joint It enables swinging and rotating movements due to acetabulum. Allow movement in all directions. The shoulder and hip joint Gliding joint It enables rotation or angular movement of the bones It is located between the surfaces of two flat bones in the ankles, wrist, and spine.

Analyze illustration and complete table given below. Movement Stimuli Plant part that moves Direction of movement light stem root It moves against the direction of the stimulus. Geotropism stem root It moves towards the direction of the stimulus. water stem root Haptotropism touch stem It moves towards or around the object that causes the stimulus. Chemotropism Presence of chemicals pollen tube It moves towards the direction where the chemicals chemical is present.

Movement Stimuli Plant part that moves Direction of movement Phototropism light stem It moves towards the light root It moves against the direction of the stimulus. Geotropism earth stem It grows upwards against the force of gravity. root It moves towards the direction of the stimulus. Hydrotropism water stem It grows upwards against the water. root It grows towards the water. Haptotropism touch stem It moves towards or around the object that causes the stimulus.
