The humerus- A long bone of the upper forelimb. It articulates proximally with the scapula to form the soulder joint and distally with the radius and ulna to form the elbow joint. <span>Proximally the humerus has a rounded projection known as the head. </span>
Cranially at the lateral aspect of the head is a large prominence- the greater tubercle. The lesser tubercle lies medially. Both tubercles act as a sight for muscle attachment. At the distal end of the humerus is a condyle which articulates with the radius & ulna & forms part of the elbow.
The diaphysis of the humerus is twisted. <span>In the dog a supra condylar foramen is present- a large hole in the condyle. </span> The Femur-This is the thigh bone and is the largest bone in the body, it is a long bone and is similar in structure to the humerus in that it has a head, neck, shaft & lateral & medial condyles. The femoral head articulates with the acetabulum proximally to form the hip joint, lateral to the head is the greater trochanter and on the medialTh side is a lesser trochanter (for muscle attachment). At the distal end of the femur are 2 condyles that articulate with the tibia to form the stifle joint. Between the 2 condyles is the trochlear groove along which the patella can move.
Tundra is a biome that is located in the coldest regions of the world. This is characterized by short growing seasons and low temperatures. The plants growing in these regions are short perennials.
<span>Their electrons are far away from the nuclei of the atoms. Transfer high-energy electrons from NADH and FADH2 to protein complexes of the electron transport chain. </span>
Producing plants by vegetative propagation is faster than growing plants from seeds. ... Therefore, farmers prefer the method of vegetative reproduction for growing plants.
