Each perimysium contains cylindrical shaped muscle fibers called sarcoplasm.Exist in bundles that are enclosed in connective tissue called the perimysium.Striated Muscle- contains dark bands that cross each muscle fiber. Motor neurons transmit a response reaction to the stimulated tissue.The interneurons in the brain process the “message” and determine a response.Sensory neurons carry stimuli message to the brain and spinal cord.Receptors in the skin identify touch or other stimuli.Motor Neurons- carry the impulses away from the brain and spinal cord.Interneurons- processes the impulses received from sensory neurons inside of the brain and spinal cord.Sensory Neurons- carry impulses from internal and external stimuli to the brain and spinal cord.Neurons control different parts of the reaction to stimuli based on their type and function:.Neurons are cells that conduct impulses in the nervous system.Skeletal System Physiology Practice with cow and horse skeleton Unit 3 Lesson 3 Bone tissue requires adequate nutrition to function properly. Bone tissue contains blood, lymph vessels and nerve fibers that continue to grow and repair themselves over the life of the animal. Transformation of cartilage to bone occurs when specialized cells called osteocytes break down the cartilage and replace it with bone tissue.Remaining cartilage is found in joints or other specialized structures. As the mammal develops, most cartilage is replaced as bone tissue.Cartilage is tough yet flexible and elastic connective tissue.Embryo skeletal development begins as cartilage.
