The body is divided into ____ by a coronal plane.
Any vertical plane that separates the body into ventral (anterior) and dorsal (posterior) segments is known as a coronal plane. From one side of the body (right) to the other, a coronal plane will pass across it (left).
Identify the suture that joins the occipital and parietal bones.
The skull's bones are joined together by fibrous joints. The occipital bone and the parietal bones are connected by a fibrous connection called the lambdoid suture, which is located on the back of the skull.
The frontal and parietal bones are connected by the coronal suture. The parietal bones are connected to one another by the sagittal suture. The parietal and temporal bones form the squamous suture joints. The two frontal bones are connected by the metopic suture.
That which follows is not a part of the scapula?
The head of the humerus and the acromion of the clavicle are housed in the shoulder joint by the scapula, which is situated posterior to the ribs.
The head of the humerus contacts with the glenoid fossa, while the acromion of the clavicle interfaces with the acromion process. The coracoacromial ligament supports and defends the shoulder muscles as it passes between the acromion process and coracoid process. A separated shoulder is the result of injury to this ligament. The suspranitus muscle originates from the supraspinous fossa, which is situated on the back of the scapula.
At the elbow, the coronoid process on the ulna connects to the coronoid fossa on the humerus. The coronoid process can fracture due to injury or elbow dislocation.
Which of the following is the meaning of the word "mental"?
The frontmost point of the mandible is known as "metal" (chin). In the chin is another somatic nerve known as the mental nerve.
The term "cranial" is related with the skull, "otic" is associated with the ear, and "nasal" is associated with the navel.
Which of the following does not contribute to the rib's attachment to the sternum?
The sternum and rib bones do not directly touch, but rather, hyaline cartilage patches connect them. A costochondral joint forms where the rib and cartilage meet. A sternocostal joint is the point where the sternum and cartilage meet. Sternocostal joints are synovial joints that are only marginally articular.
The junction between the sternal end of the clavicle and the manubrium of the sternum is known as the sternoclavicular joint.
Which facial bone is necessary for the lateral wall of the orbitals to form?
The zygomatic bones, commonly known as the cheekbones and located on the sides of your face, are what make up the lateral portion of the orbitals, despite the fact that many other structures are involved in the creation of the orbit.
The medial boundary of the orbit is formed by the lacrimal bone, which also creates the superior portion of the orbit. The zygomatic bone extends into the lateral border, while both the maxillary and zygomatic bones are a portion of the inferior border. The posterior wall is made up of the sphenoid and ethmoid bones, with the sphenoid region lateral to the ethmoid region.
Which of the following best sums up the spine's main curves?
The embryo's original shape is reflected in the primary curves of the spine, which are concave to the anterior. Examples of primary spinal curves are the thoracic and sacral curves. Kyphosis is the over-curving of these curves.
Secondary curves that are concave to the posterior include the cervical and lumbar curves. The lordosis of these curves is their exaggeration.
Which of the following is not a rotator cuff muscle?
The suspraspinatus, infraspinatus, teres minor, and subscapularis are the four muscles that make up the rotator cuff. Together, these muscles help to support the shoulder joint. Supraspinatus abducts the arm, infraspinatus and teres minor rotate it externally, and subscapularis rotates it internally. Because it is the most exposed and superior of the four muscles, the suspraspinatus sustains the majority of rotator cuff injuries.
The teres major does not insert on the head of the humerus like the rotator cuff muscles, but it does adduct and internally rotate the arm at the shoulder. In contrast, it enters more deeply into the shaft and plays a smaller role in shoulder stability.
Which of the above locations is close to the hamate?
One of the carpals in the wrist is called the hamate. Eight carpal bones are present, generally arranged in two rows. When the carpals meet the ulna and radius, the triquetral, lunate, and scaphoid are lined up in a row from medial to lateral. The pisiform sits in a slightly different plane than the other carpals and is situated anterior to the triquetral. The other carpals, the hamate, capitate, trapezoid, and trapezium, are distal to the row made by the triquetral, lunate, and scaphoid (ordered medial to lateral).
In the ankle and foot are tarsal bones called the cuboid and navicular.
Which of the following leg muscle groups enables one to stand on one's toes?
Reduced angle between the rear of the leg and the sole of the foot is known as plantar flexion. The flexor hallucis longus and the flexor digitorum make up the plantar flexors, which are located in the posterior compartment of the lower leg. These muscles work to flex the phalanges of the foot in addition to plantar flexion (toes).
Which of the following is not a muscle group that makes up the quadriceps?
There are four distinct regions of the quadriceps muscle group, each with a unique origin. The anterior inferior iliac spine is where the rectus femoris begins. (AIIS). The greater trochanter of the femur is where the vastus lateralis begins. The femur's shaft is where the vastus medialis develops. The quadriceps muscles cooperate to straighten the knee and extend the leg.
The biceps femoris is a member of the hamstring muscle group and is situated posterior to the femur. The biceps femoris' main function is to flex the leg by bending the knee.
