Example Questions
Example Question #1 : Joints
Which of the following is a term for movement along a sagittal plane that decreases the angle between bones?
Adduction
Extension
Flexion
Abduction
Flexion
Movement along a sagittal plane that decreases the angle between bones is flexion. This is in contrast to extension, which is movement along a sagittal plane that increases the angle between bones. Adduction is movement that pulls a structure toward the midline of the body, while abduction moves a structure away from midline.
Example Question #6 : Joints
Which of the following joints is capable of circumduction?
The elbow
The knee
The shoulder
The sacroiliac joint
The shoulder
Circumduction is movement that produces a circular motion wth the distal end of a body part. True circumduction allows for a 360 degree range of movement. Of the joints listed, the only one capable of circumduction is the shoulder.
Example Question #1 : Joints
Which of the following is an example of a condyloid joint?
The humeroradial joint
The glenohumeral joint
The metacarpophalangeal joints
The acromioclavicular joint
The metacarpophalangeal joints
Condyloid joints are a form of synovial joint in which a condyle rests in an ovoid cavity. Of the joints listed, the only condyloid joint is the metacarpophalangeal joints (the joint of the most proximal knuckle).
The acromioclavicular joint is a plane joint, while the glenohumeral and humeroradial joints are both ball and socket joints.
Example Question #8 : Joints
The patella articulates with which of the following bones?
The tibia
The femur
The fibula
The tibia and fibula
The femur
The only bone that the patella, or kneecap, articulates with is the femur, at the patellofemoral joint. The patella is a sesamoid bone, meaning it is fully embedded within a tendon. The patellar ligament joins the patella to the tibial tuberosity (but not the fibula).
Example Question #7 : Joints
Which of the following are three structural classifications of joints?
Sutures, syndesmosis, gomphosis
Synarthrosis, ampiarthrosis, and diarthrosis
Condyloid, gliding, and hinge
Fibrous, cartilaginous, and synovial
Fibrous, cartilaginous, and synovial
The structural classification of joints divides them according to the form of tissue that connects bones to each other. The three structural divisions of joints are fibrous, cartilaginous, and synovial. In contrast, synarthrosis, amphiarthrosis, and diarthrosis are all classifications of a joint's movement.
Condyloid, gliding, and hinge joints are all types of synovial joints, while sutures, syndesmosis, and gomphosis are all types of fibrous joints.
Example Question #2 : Joints
Gomphosis joints are fibrous joints found between the __________.
tooth and socket
tibia and fibula
skull bones
radius and the ulna
tooth and socket
Gomphosis joints are fibrous joints that attach the root of the tooth to the bony socket of the mandible or maxilla.
Both the tibio-fibular joint and the joint between the radius and ulna are syndesmoses, while the joints between the bones of the skull are sutures.
Example Question #11 : Joints
__________ joints make up the majority of the joints of the human body.
Fibrous
Synarthrosis
Synovial
Amphiarthrosis
Cartilaginous
Synovial
The majority of joints of the human body are synovial joints. These joints are diarthrotic and include a synovial joint capsule that allows for greater freedom of movement. Examples include the fingers and the elbows, the knees, the temporomandibular joint, and the hips.
Fibrous and cartilagenous joints, all of which are either synarthrotic or amphiarthrotic, are relatively less common.
