Supraglenoid tubercle- serves as the proximal attachment for the long head of the biceps 3. Infraglenoid tubercle- marks the proximal attachment for the long head of the triceps Distal Humerus 1. Trochlea- spool shaped structure located on the medial side of the distal humerus that articulates with the ulna to form the humeroulnar joint 2. Coronoid fossa- a small pit located just superior to the trochlea that accepts the coronoid process of the ulna when the elbow is fully flexed. 3.
The proximal end of the humerus feature a rounded head that articulates with glenoid cavity of the scapula to form the shoulder joint. 2. Which bone is Stefan placed referring to as the collarbone? B. Stefan is referring to the clavicle 3. Which surface marking could Stefan use to distinguish the right humerus for the left?
Suture joints and Gomphosis joints are synarthroses. c. Syndesmoses: there is a greater distance between the bones and more fibrous connective tissue. The tissue is either arranged as a bundle (ligament) or as a sheet (interosseus membrane). Example tibia/fibula, because it permits slight movement, a syndesmosis is classified functionally as an amphiarthrosis. Functionally, sutures are classified as synarthroses because they are immovable; syndesmoses are classified as amphiarthroses because they are slightly movable.
The subtalar joint is formed between the bottom of the talus and the calcaneus, and it consists of two separate joint cavities anteriorly and posteriorly. The anterior joint cavity is named the anterior subtalar joint and is formed by the head of the talus, the anterior-superior facets, the sustentaculum tali of the calcaneus, and the concave proximal surface of the tarsal navicular. The latter is termed the posterior subtalar joint and is formed by the inferior posterior facet of the talus and the superior posterior facet of the calcaneus. The subtalar joint as a whole is supported by the deep ligaments, the peripheral ligaments, and the retinacula. As a whole, the ligaments stabilize the joint and separate the anterior and posterior joint capsules.
Its deep crimson color indicates the presence of oxygen-rich blood (Tortora, Derrickson 2006). There is a web of smaller veins and capillaries which will sometimes obstruct the view. The road continues north to the pelvic cavity. The bones of the pelvis are the coxal bones which include the pelvis, ischium, and iliam, the coccyx, and the sacrum (Thibodeau, Patton 2008). Slightly to the right lies the urinary bladder and superior to it is the uterus, with the right ovary and fallopian tube lateral to it.
In compact bones, blood vessels pass through the bones periosteum, the membrane surrounding the bone, and the endosteum through perpendicular channels known as the perforating canals. These canals are conjoined with the central canal, also known as the Haversian canal, which runs the length of the bone, and houses the blood vessels and nerve cells. Surrounding the central canal are layers of bone that are often remnants of previous Haversian systems, called lamellae. Inside the layers of the lamellae are small chambers containing osteocytes, or bones cells. These chambers are known as lacunae.
c. Gallbladder—lies on posterior side of the liver. d. Pancreas—located behind the stomach, attached to the duodenum. 3. Name the four layers of the wall of the alimentary canal. a. Mucosa or mucous membrane b. Submucosa c. Muscular layer d. Serosa or serous layer 4.
In order for the ribs to expand, the ribs need something to allow movement. Cartilage allows this. Cartilage is a softer, flexible (but very strong) material found in joints around the body. Cartilages attach the ribs to the breastbone (sternum) and the sternum to the collarbones (clavicles). The joints between the ribs and the cartilages are called the costochondral joints.
A unique joint, the shoulder has only one bony attachment to the rest of the skeleton in the clavicle - collarbone - where it attaches to the scapula. This unique anatomy allows a wide range of motion for the shoulder joint. · HINGE JOINTS, e.g. the knee or elbow joint, can straighten or bend in the same way as a door hinge opens or closes. · Knee joint - range of motion is typically measured using a tool called a goniometer.
Several of these fibers may be part of the formation of the tunnel for the flexor hallucis longus tendon. In addition, a band of strands merge with the posterior intermalleolar ligament [29]. The posterior intermalleolar tendon has been the focus of current studies as a result of its contribution in the posterior soft tissue impingement disorder at the ankle joint[17, 27]. Its high frequency in incidence in radiological, and anatomical studies contrast extensively, extending from 19% up to 100% [24, 27, 30]. Springer ( ) noted that in cadaveric dissection the intermalleolar ligament was found consistently.
