The superior pubic ramus is the segment of bone that passes laterally from the pubic body to join the ilium. The narrow ridge running along the superior margin of the superior pubic ramus is the pectineal line of the pubis.
Which coxal bone contains the anterior and posterior gluteal lines?
The lateral surface of the ilium has 3 rough curved lines: the posterior, anterior, and inferior gluteal lines. Medially, the ilium has an iliac fossa. Posteriorly, the medial aspect of the ilium has an auricular surface. The ischium is the inferior aspect of the pelvis.
What bone articulates with posteromedial portion of the os coxae?
The sacral promontory is the anterior midline projection of the sacral plateau. d. The alae, or “wings,” are those parts of the first sacral element that sweep laterally from the centrum. Each ala articulates laterally with the posteromedial surface of an os coxae.
Which coxal bone contains the anterior and posterior gluteal lines quizlet?
The anterior surfaces of each ischium contribute to the formation of the anterior joint of the pelvic girdle. Each ischium completely surrounds the obturator foramen. The ischium is the posterior inferior portion of the hip bone and is composed of a superior body and an inferior ramus.What coxal bone forms a symphysis joint?
The pubis forms the most anterior portion of the pelvic girdle and joins the two coxal bones together at the pubic symphysis joint. The ilium is the largest and the most superior of the three bones that form the coxa (hipbone or hip joint).
Which joint consists of a fibrocartilage pad that joins the two pubic bones anteriorly?
At the pubic symphysis, the pubic portions of the right and left hip bones of the pelvis are joined together by fibrocartilage pad.
Where is the Pectineal line?
The pectineal line of the pubis (also pecten pubis) is a ridge on the superior ramus of the pubic bone. It forms part of the pelvic brim. Lying across from the pectineal line are fibers of the pectineal ligament, and the proximal origin of the pectineus muscle.
Which bones articulate at the glenohumeral joint?
The shoulder joint itself known as the Glenohumeral joint, (is a ball and socket articulation between the head of the humerus and the glenoid cavity of the scapula)Which tarsal bone articulates with both the tibia and fibula?
The proximal row contains the talus, which is the most superior of the tarsals and articulates with the tibia and fibula to form the ankle joint.
Which of the following bones form the obturator foramen?Anatomical terms of bone The obturator foramen (Latin foramen obturatum) is the large opening created by the ischium and pubis bones of the pelvis through which nerves and blood vessels pass.
Article first time published onWhich part of the os coxae is in the inferior posterior section of the pelvic girdle?
Ischium Anatomy Landmarks and Features Now let’s talk about the ischium of the hip bone (coxal bone), which is the lower rear portion (or posterior inferior region) of the hip bone.
Where is the os coxae?
The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large flat bone, constricted in the center and expanded above and below. In some vertebrates (including humans before puberty) it is composed of three parts: the ilium, ischium, and the pubis.
What is the function of the os coxae?
The two hip bones (also called coxal bones or os coxae) are together called the pelvic girdle (hip girdle) and serve as the attachment point for each lower limb.
Is OS Coxae axial or appendicular?
The bones of the appendicular skeleton include those of the appendages and the joints with those appendages including the shoulder girdle (clavicle and scapula) and the hip joint (os coxae or hip bones).
Where is the fovea capitis located?
The fovea capitis is a small, oval-shaped dimple on the ball-shaped end (head) on top of your femur (thigh bone). Your hip is a ball-and-socket joint. The femoral head is the ball.
What are 3 regions on each OS Coxae?
Each os coxa is formed by the fusion of three bones: ilium, ischium, and pubis.
What does the pectineal line separate?
Anatomical terminology The pectinate line (dentate line) is a line which divides the upper two-thirds and lower third of the anal canal. Developmentally, this line represents the hindgut-proctodeum junction.
Is pectineal line the same as spiral line?
While the spiral line, which provides the origin for the vastus medialis muscle, runs medially towards the lesser trochanter, the pectineal line, marking the insertion of the pectineus muscle, is located lateral and superior to it [15].
What inserts on the pectineal line?
Pectineus muscle inserts into the posterior surface of femur, along the pectineal line and proximal part of linea aspera.
Which joint consists of a fibrocartilage?
A symphysis (fibrocartilaginous joint) is a joint in which the body (physis) of one bone meets the body of another. All but two of the symphyses lie in the vertebral (spinal) column, and all but one contain fibrocartilage as a constituent tissue.
What is the name of the cartilaginous disc that joins the pubic bones anteriorly?
The pubic symphysis is a unique joint consisting of a fibrocartilaginous disc sandwiched between the articular surfaces of the pubic bones. It resists tensile, shearing and compressive forces and is capable of a small amount of movement under physiological conditions in most adults (up to 2 mm shift and 1° rotation).
What is an example of a Synarthrotic joint?
A synarthrosis is a joint that is essentially immobile. This type of joint provides for a strong connection between the adjacent bones, which serves to protect internal structures such as the brain or heart. Examples include the fibrous joints of the skull sutures and the cartilaginous manubriosternal joint.
Does fibula articulate with calcaneus?
The talus articulates with four bones – the tibia, fibula, calcaneus and navicular. Within the tarsus, it articulates with the calcaneus below and the navicular in front within the talocalcaneonavicular joint. … A lateral extension of this surface forms an articular facet with the fibular malleolus.
Which tarsal bone articulates with both the tibia and fibula quizlet?
The tibia and fibula articulate with the talus bone of the ankle to form this.
What articulates with the fibula?
The head of the fibula forms the proximal end and articulates with the underside of the lateral condyle of the tibia. The distal fibula articulates with the fibular notch of the tibia. The expanded distal end of the fibula is the lateral malleolus.
Which of the following bones articulate with the metatarsal bones?
The metatarsal bones are convex on their dorsal surfaces but concave on their plantar surfaces. The proximal base articulates with one or more of the distal tarsal bones; namely the cuboid and the cuneiform bones. These articulations are known as the tarsometatarsal joints.
Which bone articulates with the scapula at the glenoid cavity?
part of scapula …presents a shallow cavity, the glenoid cavity, which articulates with the head of the bone of the upper arm, the humerus, to form the shoulder joint.
Which of the following bones articulates with the phalanges?
A broad, flat sheet of connective tissue called an interosseous membrane connects the bones of the forearm (radius and ulna). The distal phalanges articulate with the metacarpals and the proximal phalanges.
What attaches to the obturator foramen?
The obturator nerve emerges from the medial side of the psoas muscle, crosses the lesser pelvis, and passes through the obturator foramen into the medial thigh, innervating the adductor longus, brevis, and magnus; gracilis; obturator externus; and pectineus muscles, whose action is to adduct the thigh.
Where is obturator groove?
The obturator groove is located on the pelvic floor, craniolateral to the obturator foramen for the passage of the obturator nerve.
What are the contents of obturator foramen?
The contents of the obturator canal are the obturator nerve, artery and vein.
