Example Question #431 : Human Anatomy And Physiology
The interosseous membrane between the tibia and fibula is an example of what kind of joint?
Synchondrosis
Gomphosis
Syndesmosis
Suture
Cartilagenous
Syndesmosis
A syndesmosis is a type of immovable fibrous joint that is made up of collagen. This same interosseous membrane also exists between the radius and ulna. Sutures and gomphoses are other examples of fibrous joints.
Example Question #432 : Human Anatomy And Physiology
The joints of the knuckles are examples of __________ joints.
gliding
hinge
ball-and-socket
condylar
saddle
condylar
Condylar or ellipsoid joints involve one bone that is concave and one bone that is convex. The metacarpophalangeal joints of the knuckles, as well as the wrist joint, are both condylar. As for the other bones of the hand, the intercarpal joints are gliding and the interphalangeal joints are hinge.
Example Question #433 : Human Anatomy And Physiology
Sternocostal joints are all gliding joints, except the __________.
articulation of the seventh rib to the sternum, which is a synchondrosis
articulation of the first rib to the sternum, which is a synchondrosis
articulation of the seventh rib to the sternum, which is a synostosis
articulation of the first rib to the sternum, which is a syndesmosis
articulation of the first rib to the sternum, which is a synchondrosis
Where the first rib meets the manubrium (top of sternum), the joint is cartilaginous and called a synchondrosis. Syndesmoses are fibrous joints of connective tissue, and syostoses are areas of bone fusion.
Example Question #434 : Human Anatomy And Physiology
The radiocarpal joint differs from the intercarpal joints in that __________.
the radiocarpal joint is a gliding joint, and the intercarpal joints are condylar joints
the radiocarpal joint is a hinge joint, and the intercarpal joints are gliding joints
the radiocarpal joint is a condylar joint, and the intercarpal joints are hinge joints
the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints
the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints
The radiocarpal or wrist joint is a condylar synovial joint because the radius has a concave surface, and the carpals have a convex surface. The joint connects the radius with the scaphoid, lunate, and triquetrum.
Example Question #435 : Human Anatomy And Physiology
Which of the following is not involved in joining a rib to the sternum?
Synovial joint
Sternocostal joint
Costochondral joint
Sternoclavicular joint
Hyaline cartilage
Sternoclavicular joint
The rib bones do not directly interface with the sternum, but are linked to the sternum by regions of hyaline cartilage. The interface between the rib and the cartilage is a costochonral joint. The interface between the cartilage and the sternum is a sternocostal joint. Sternocostal joints are slightly articular synovial joints.
The sternoclavicular joint is the interface between the sternal end of the clavicle and the manubrium of the sternum.
Example Question #436 : Human Anatomy And Physiology
Name the suture that connects the parietal bones to the occipital bone.
Squamous suture
Sagittal suture
Lambdoid suture
Coronal suture
Metopic suture
Lambdoid suture
Fibrous joints are responsible for connecting the bones of the skull. The lambdoid suture is the fibrous joint found on the posterior portion of the skull, and is used to connect the occipital bone to the parietal bones.
The coronal suture connects the frontal bones and parietal bones. The sagittal suture joins the parietal bones to one another. The squamous suture joins the parietal and temporal bones. The metopic suture joins the two frontal bones to one another.
Example Question #3 : Identifying Joints Of The Trunk, Core, And Head
Which of the following pairs of vertebrae represents the location of the atlantoaxial joint in the spine?
T1 and T2
C1 and C2
M1 and M2
None of these
L1 and L2
C1 and C2
The atlantoaxial joint, a trochoid (pivot) joint where most cervical rotation occurs, sits at the junction of the atlas (C1) and axis (C2). It is the most mobile joint to occur between any two vertebrae in the human body.
Example Question #3 : Identifying Joints Of The Trunk, Core, And Head
Which of the following is not a joint articulation found in the thoracic cavity?
Costochondral
Sternoclavicular
Acromioclavicular
Sternocostal
Acromioclavicular
The thorax has three major articulations: sternoclavicular, sternocostal, and costochondral joints. The sternoclavicular provides a connection between the upper limbs and the axial skeleton, joining the manubrium of the sternum to the medial end of the clavicle. The sternocostal joints are the attachments between the sternum and the cartilage of ribs 1 to 7. Costochondral joints are the attachments of the ribs to their costal cartilages.
The acromioclavicular joint is formed between the acromion process of the scapula and the distal end of the clavicle. It is local to the shoulder, and is not found in the thoracic cavity.
Example Question #5 : Identifying Joints Of The Trunk, Core, And Head
What three bones make up the shoulder joint?
Coracoid process, clavicle, and scapula
Humerus, scapula, and clavicle
Humerus and scapula only
Femur, scapula, and clavicle
Scapula and clavicle only
Humerus, scapula, and clavicle
The three bones that make up the shoulder joint are the humerus, scapula, and clavicle. The head of the humerus articulates with the glenoid cavity of the scapula and the clavicle articulates with the scapula at the acromioclavicular joint. Collectively these make up the shoulder joint.
Example Question #6 : Identifying Joints Of The Trunk, Core, And Head
Because of human development, this type of joint only completely fuses later in life.
Sutures
Syndesmoses
Gomphoses
Amphiarthroses
Synovial
Sutures
The sutures of the skull are not fused at childbirth possibly to ease passage of the skull through the birth canal. Later in life the sutures fuse to form synarthroses called synostoses and offer much stronger protection of the brain. Fontanelles are the soft spots between the skull bones and will close about 18 months after birth.
