Unit 4.1 Vocabulary

The point of contact between elements of an animal skeleton whether movable or rigidly fixed together with the surrounding and supporting parts (as membranes, tendons, or ligaments)

• Muscle

• Joint

• Sarcomere

• Plexus

The range through which a joint can be moved

• Joint

• Goniometer

• Contraction

• Range of Motion

A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures (as some joints, respiratory passages, and the external ear) is replaced by bone during ossification in the higher vertebrates.

Goniometer

• An instrument for measuring speed

• An instrument for measuring angles (as of a joint or the skull)

• An instrument for measuring length (as of a size or the skull)

• An instrument for measuring weight

An organ composed of one of the three types of fibrous tissue (skeletal, cardiac, and smooth), specialized for contraction to produce voluntary and involuntary movements of parts of the body

• Nervous Tissue

• Bone

• Skin

• Muscle

An organ specialized for contraction, composed of striated muscle fibers (cells), supported by connective tissue, attached to bone by a tendon or aponeurosis, and stimulated by somatic motor neurons
