The differences between cardiac, skeletal, and smooth muscle structures are easy to determine when the three models in this set are compared side by side. The cardiac muscle cell, enlarged 1,500X, is dissected to display syncytial fiber arrangement and Purkinje cells; the skeletal muscle, enlarged 1,000X, shows the union with both and tendon, and sarcolemma; and the smooth muscle, enlarged 2,500X, exhibits the capillary and motor end plate of the autonomic nerve. All models are cross sectioned to display myofibrils. Also illustrated are the associated nerves, blood vessels, connective tissue, cell nuclei, and nerve endings. Each model in this set is a three-dimensional depiction of the muscle fibers students study on microscope slides, and each is made from durable plastic resin for years of classroom use. The models are mounted on individual bases. You will receive a key for each model, allowing you to identify a total of 40 structures. Size of each: 11″L x 4″W x 6″H.
