Outcome 1 Understand anatomy and physiology in relation to moving & positioning individuals. 1.1 Bones and muscles are concerned with the movement of the body. The skeleton is a rigid framework that gives shape and support to the body and is jointed to permit movement. The vertebral column is the basis of the skeleton and consists of a series of bony rings united by inter-vertebral discs of cartilage. All bones give attachment to muscles, which are responsible for 50% of our body weight and also permit movement.
Shubin shows how fin structures of fish like Tiktaalik mark the beginning of the evolution into the mammalian paw and opposable thumb structures in the hands of today’s primates. The significance behind Tiktaalik is how it proved to be the missing link which greatly shows the transition from fish who swim, to four-legged vertebrates. Neil also states that all creatures in the world are built similarly to one another. Creatures such as whales, birds, and humans have single arm bones that each lead to two others, that connect to fingers or our toes. In us humans, this shows up in the humorous, and they go through the radius and ulna into our wrist bones and fingers.
5. Which ossification method would form a femur? The femur, which is a long bone, is formed by endochondral ossification which is the replacement of cartilage by osseous tissue. Most bones of the body are formed by this process. 6.
One of the types of tissue that makes up bone is the mineralized osseous tissue, also called bone tissue, that gives it rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.
The human skeleton Is made up of 206 bones. The functions of the skeleton are to provide support, give our bodies shape, and provide protection to other systems and organs of the body, to provide attachments for muscles, to produce movement Joints A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilagenous (partially moveable) and the Synovial (freely moveable) joint. Fibrous joints Fibrous (synarthrodial): This type of joint is held together by only a ligament. Examples are where the teeth are held to their bony sockets and at both the radioulnar and tibiofibular joints.

Which parts of the frog’s nervous system can be observed in its abdominal cavity and hind leg? A. The vertebrae contained the spinal cord is visible. You can also see the spinal cord branch into two cords. One nerve cord runs to the right leg and one nerve cord runs to the left leg.
Although different species may vary in size or color, almost all frogs have the same basic body structure. They have large hind legs, short front legs, and a flat head and body with no neck. Adult frogs have no tail, though one North American species has a short, tail like structure. Most frogs have a sticky tongue attached to the front part of the mouth. They can rapidly flip out the tongue to capture prey.
