Q: What kind of joints are capable of a wide range of movements, classified as gliding, angular, rotational, or special? Read this paragraph and choose the correct option from the provided answers: Movement at Synovial Joints The wide range of movement allowed by synovial joints produces different types of movements. The movement of synovial joints can be classified as one of four different types: gliding, angular, rotational, or special movement. Gliding Movement Gliding movements occur as relatively flat bone surfaces move past each other. Gliding movements produce very little rotation or angular movement of the bones. The joints of the carpal and tarsal bones are examples of joints that produce gliding movements. Angular Movement Angular movements are produced when the angle between the bones of a joint changes. There are several different types of angular movements, including flexion, extension, hyperextension, abduction, adduction, and circumduction. Flexion, or bending, occurs when the angle between the bones decreases. Moving the forearm upward at the elbow or moving the wrist to move the hand toward the forearm are examples of flexion. Extension is the opposite of flexion in that the angle between the bones of a joint increases. Straightening a limb after flexion is an example of extension. Extension past the regular anatomical position is referred to as hyperextension. This includes moving the neck back to look upward, or bending the wrist so that the hand moves away from the forearm. Abduction occurs when a bone moves away from the midline of the body. Examples of abduction are moving the arms or legs laterally to lift them straight out to the side. Adduction is the movement of a bone toward the midline of the body. Movement of the limbs inward after abduction is an example of adduction. Circumduction is the movement of a limb in a circular motion, as in moving the arm in a circular motion. Choices: - glandular - locking - fibrous - synovial A:
synovial

Q: Which system of the body is responsible for bringing air into the body? Read this paragraph and choose the correct option from the provided answers: We breathe because we need oxygen. Breathing also releases carbon dioxide from our bodies into the air. The respiratory system is the body system that brings air containing oxygen into the body and releases carbon dioxide into the atmosphere. Recall that oxygen is needed to make ATP. Choices: - vascular system - excretory system - digestive system - respiratory system A:
respiratory system

Q: Bacteria are responsible for many types of what in humans? Read this paragraph and choose the correct option from the provided answers: Bacteria are responsible for many types of diseases in humans. Choices: - colors - smells - food - diseases A:
diseases
