Ligamentary
Skeleton
Demonstrate Movement with
Simulated Ligaments
Replica. Augment your orthopedic,
physical therapy, kinesthetic,
and sports medicine courses, with
this skeleton featuring simulated
ligaments, made of durable elastic.
Positioned at the right shoulder,
elbow, hip, and knee, the simulated
ligaments move the joints in a
realistic manner and help students
gain a greater understanding of how
the human body moves. Special
U-brackets allow you to slide the arm
and leg ligaments inside joints, just
like the actual human skeleton. Arms,
legs, and skull are removable; the
calvarium is sectioned; and the mandible
with maxillae and removable
teeth are dissectable. Includes dust
cover and and Ward's Osteological
Preparations Brochure identifying 115
structures. For easy transportation
and demonstration, the skeleton is
rod mounted on a stand with casters.
Size: 72"H.

SOMSO® Advanced
Muscular Skeleton
Extremely Accurate
Representations of Muscle Origins
and Insertions
Help students understand how muscle
function affects limb movement with
this exceptionally detailed skeleton. Its
right side shows muscle
origins in red and insertions
in blue; in addition,
the bones, structures, and
foramina are numbered on
its left side. Used with corresponding
muscle anatomy
models of the human
torso, arm, or leg, the
skeleton helps reinforce
the structure of human
muscles. Even the most
demanding med tech,
comparative anatomy,
and anatomy and physiology
courses will benefit
from this skeleton’s detail.
Constructed with durable
metal hardware. The rodmounted
skeleton is secured on a sturdy
wheeled base; the ring-mounted skeleton
can be suspended from the fitting secured
at the top of the skull or can be stored in a cabinet. Full size and washable, it
includes a plastic dust cover, key identifying 351 bone structures and 158
muscles, and WARD’S Osteological Preparations Brochure. Size: 67"H. Note:
The stand for ring-mounted skeletons is available separately.

Flexible
Ligamentary
Skeleton
The Most Versatile
Skeleton Available
Replica. This perfect reproduction
of a human skeleton is cast directly
from a specially selected natural
human skeleton to ensure the finest
details of bony surface are represented.
Ligaments are featured on
the hands and feet in addition to
the shoulder, elbow, hip and knee.
A flexible spine is complemented
by nerve ends and arteries, with the
muscle origins and insertions painted
on the left side of skeleton. Over
300 numbered structures, including
a sectioned calvarium, bones, bony
parts, sutures, fissures, and foramina,
are all detailed in an accompanying
key. Includes dust cover and and
Ward's Osteological Preparations
Brochure. Skeleton is rod mounted
on a stand with casters. Size: 72"H.

Sarcomere
Model
Advanced Working
Model for Muscular
Examination
The smallest functional unit
of a myofibril of striated
muscle, the sarcomere,
is shown here
with Z lines or disks at
either end. Scaled to
tens of thousands of
times its actual size,
this moving model
graphically illustrates
the sliding filament
theory of skeletal muscle
contraction. Reflecting the
most recent advances in
electron microscopic ultrastructure, the model unequivocally demonstrates
that individual myofilaments neither change shape nor shorten
— rather the proteins actin and myosin slide past one another, resulting
in the shortening of the sarcomere itself. The arrangement, configuration,
and function of thin filaments (actin, troponin, tropomyosin), and thick filaments
(myosin II), the M-line and Z-line are all clearly depicted. Applications
for ths model include physiology classes, athletic trainer education, sports
medicine specialists, physical and massage therapists, and more. The working
sarcomere model helps bridge the link between cellular physiology
and muscle tone, muscle cramps, knots and tears. Model also features a
translucent sheath representing the sarcoplasmic reticulum, which can be
wrapped around the sarcomere to offer greater understanding of membrane
action potentials and the role calcium ion transport plays in muscle
contraction. Includes a user manual. Size: 22"L x 6"W x 8"H.
