What bone is held to the body by the pectoral girdle?
The pectoral girdle, consisting of the clavicle and the scapula, attaches each upper limb to the axial skeleton. The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint.
Where does the humerus articulate on the pectoral girdle quizlet?
The scapula has a glenoid cavity that is the site of articulation with the humerus in the pectoral girdle.
What are the two bones of the pectoral girdle quizlet?
The Pectoral (shoulder) Girdle is part of the appendicular skeleton and consists of the clavicle and scapula posteriorly.
Is the collar bone axial or appendicular?
The appendicular skeleton is everything else. It’s everything that attaches on to the axial skeleton. Think “appendages”. The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.
What 3 bones make up the shoulder girdle and how is it linked to the axial skeleton?
The shoulder girdle or pectoral girdle is the set of bones in the appendicular skeleton which connects to the arm on each side. In humans it consists of the clavicle and scapula; in those species with three bones in the shoulder, it consists of the clavicle, scapula, and coracoid.
Which muscles attach the scapula to the axial skeleton?
The medial/vertebral border of the human scapula is the longest of the three borders and serves as the insertion point for four muscles connecting the scapula to the axial skeleton: one connects it to the costal surface (serratus anterior) and three to the medial/cranial aspect (major and minor rhomboids, and levator …
What muscle is pectoral girdle?
Muscles that position the pectoral girdle are located either on the anterior thorax or on the posterior thorax (Figure 7.26). The anterior muscles include the subclavius, pectoralis minor, and serratus anterior. The posterior muscles include the trapezius, rhomboid major, and rhomboid minor.
Which feature of the ulna forms the point of the elbow?
The upper end of the ulna presents a large C-shaped notch—the semilunar, or trochlear, notch—which articulates with the trochlea of the humerus (upper arm bone) to form the elbow joint.
What attaches the scapula to the trunk of the body?
The clavicle, or collarbone, is a slender s-shaped bone that extends between the sternum and the scapula and is located directly above the first rib. It functions to attach the upper arm to the trunk and provides support to allow free movement around the shoulder.
Which bone is part of the appendicular skeleton quizlet?
The clavicle, shoulder girdle, humerus, pelvic girdle, and femur are part of the appendicular skeleton.
What is the appendicular and axial skeleton?
The 80 bones of the axial skeleton form the vertical axis of the body. They include the bones of the head, vertebral column, ribs and breastbone or sternum. The appendicular skeleton consists of 126 bones and includes the free appendages and their attachments to the axial skeleton.
Is the coccyx part of the appendicular skeleton?
The coccyx, or tailbone, is formed by a fusion of four vertebrae. The bones of the human skeleton are divided into two groups. The appendicular skeleton includes all the bones that form the upper and lower limbs, and the shoulder and pelvic girdles.
Is the sphenoid axial or appendicular?
The cranial bones, including the frontal, parietal, and sphenoid bones, cover the top of the head. The facial bones of the skull form the face and provide cavities for the eyes, nose, and mouth. Although it is not found in the skull, the hyoid bone is considered a component of the axial skeleton.
Where is the area that connects the axial skeleton and attaches to the pelvic girdle and the appendicular skeleton of the lower extremity?
The pelvic girdle is formed by a single hip bone. The hip bone attaches the lower limb to the axial skeleton through its articulation with the sacrum. The right and left hip bones, plus the sacrum and the coccyx, together form the pelvis.
What makes up the appendicular skeleton Brainly?
The appendicular skeleton is made up of the limbs of the upper and lower limbs. The pectoral girdle is composed of the clavicles and the scapulae. The upper limb contains 30 bones in the arm, the forearm, and the hand. The pelvic girdle attaches the lower limbs to the axial skeleton.
What is the appendicular skeleton quizlet?
Appendicular Skeleton. Consists of the bones of the upper and lower limbs, together with the shoulder girdle and the pelvic girdle. The bones of the limbs are attached to the axial skeleton by the means of the shoulder girdle and the pelvic girdle.
What is the difference between the axial and appendicular skeleton quizlet?
What is the difference between the axial and appendicular skeleton? … The axial skeleton makes up our central axis and consists of the following bones: skull, vertebrae, ribs and sternum. The appendicular skeleton consists of the limbs and girdles.
What are 3 muscles attached only to the appendicular skeleton of the upper extremity?
The anterior muscles include the subclavius, pectoralis minor, and serratus anterior. The posterior muscles include the trapezius, rhomboid major, and rhomboid minor.
What is pectoral girdle and pelvic girdle?
The pectoral girdle stabilizes the upper limbs on the thorax and allows a range of mobility at the shoulder. … The pelvic girdle transfers upper body weight to the lower limbs by articulating with the spine.
