The first is the femur in the upper leg, the tibia and fibula in the lower leg. the first is on the basis of their structure or on the basis of their function. The structural classification divides joints into 3 parts which are fibrous, cartilaginous, and synovial joints depending on the material composing the joint also the cavity's presence in the joint. synarthroses, amphiarthroses, and diarthroses are three categories of the functional classification. Sutures are fibrous joints that work on joining the bones of the skull together and it is can be found only in the skull.
C) sarcoplasmic reticulum. D) myofibril. E) myofilament. 8) Which of the following best describes the term sarcomere? A) protein that accounts for elasticity of resting muscle B) repeating unit of striated myofibrils C) storage site for
A connective tissue sheath known as perichondrium overlies the fre surface of most cartilage. Perichondrium is vascular and its vessles suppl nutients to the cells of the cartilage. Bone- connective tissue consists of cells and exracellular matrix. Consisis of cells nd and extracellular matrix. Special feature of bone is the mineralization of tis matrix with calcium phosphate in the from of hydroxyapatite crystals which produce an extremely hard tissue capable o providing support and protection.
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?
A joint is the location at which two or more bones make contact. They are constructed to allow movement and provide mechanical support and weight bearing. 2. What is a synovial joint? Synovial joints are made up of bones that come together to formulate the joint, the ligaments attach bone to bone and allow for the joint movement to be stable and in the correct direction.
Humeroradial joint 3. Proximal radioulnar joint 4. Distal radioulnar joint The four bones that relate to the function of the elbow and forearm complex 1. Scapula 2. Distal humerus 3.
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.
The skeletal system The skeletal system is the system in our body that supplies protection to the vital organs and support for the muscles and skin. The skeletal system is the utmost important system in the body; it holds the systems together assist anting the weight of the body. This support is provided by bones, structures as strong as reinforced concrete but considerably lighter. Oppose from concrete, bones can be remodeled and reshaped to meet changing metabolic demands and patterns of activity. Bones operates with muscles to conserve body position and to construct controlled, defined movements.
Question 22: The highlighted bone is the left rib Question 23, 24, 25 This picture is a highlighted section of compact bone tissue from the femoral shaft. The unit is called an Osteons Question 26: This bone is known as a long bone. Question 27: This bone is known as an irregular
Skeleton study- human A.) ------------------------------------------------- Frontal Aspect Frontal bone: The frontal bone is made of two portion squama frontalis and Pars Orbitalis Parietal bone: Parietal bones together form the sides and the roof of the human skull (4 angles/4 borders) Temporal bone: Temporal bones support the section of the face which is known as the temple. Sphenoid bone: Shape=butterfly, this bone is one of seven which combine to form the orbit Ethmoid bone: One of the bones which make up the orbit of the eye Lacrimal groove: Nasal bone: Two small size bones that form the bridge of the nose Perpendicular Plate of the Ethmoid: it forms part of the nasal septum Nasal concha bones: Shape = shell-shaped structure Vomer: Forms the inferior and posterior part of the nasal septum. Zygomatic arch: Cheek bone; formed by the zygomatic process of temporal bone and the temporal process of the zygomatic bone. Maxilla: The maxilla is two bones which are fused along the palatal fissure which forms the upper jaw Mandible: The Mandible is the bone which forms the lower jaw and holds the lower teeth in place Mental foramen: The Mental foramen is the name given to one of two holes which are located on the anterior surface of the mandible and allows the mental nerves and vessels passage.
