- Identify the follow parts
- Types of skeleton
- hydrostatic skeleton
- exoskeleton
- endoskeleton
- Hydrostatic skeleton - found in soft bodied invertebrates, a fluid-filled cavity in encircled by the muscle fiber of an organism
- Exoskeleton - surround the body as a rigid case in most animal
- Endoskeleton - rigid internal skeleton, which muscle are attached found un vertebrates and echinoderms, have flexible exterior that accumulates the movement of their skeleton.
- Two parts of the endoskeleton of a mammal
- Axial Skeleton
- Appendicular Skeleton
- Axial Skeleton - bones forms the axis of the body and support the organ of the head, neck and chest
- Appendicular Skeleton - bones includes the limbs, pectorals and pelvic girdle
- Synergist - muscle that cause same action at the joint, all act to extend the knee joint
- Antagonist - muscle that produce opposing action, muscle that flex a joint to muscle that extend a joint
- Isotonic Contraction - the muscle and all its fiber shorten in length during contraction
- Isometric Contraction- the muscle begin to conduct but the tension is absorbed by the tendons and other elastic tissue associated
- What are the three types of joints
- Immovable joints
- Slightly movable joints
- Freely movable joints
- Immovable Joints - include the sature that joint the bones of the skull
- Slightly Movable Joints - includes those bones which are bridge with cartilage
- Freely Movable Joints - also called synovial joints = articulating ends of the bones are located within a sunovial capsule filled with a lubricated fluid
- Tendon - a dense connective tissue strap where muscle are attached to the bone
- Origin - are attachment of the muscle, remains stationary during contraction
- Insertion - the other end os the muscle which attached to another side os the bone moves when muscle contraction occurs
