25
Patella
A large flat bone that sits over the stifle joint
26
Tibia
A larger bone distal to the patella, considered the weight bearing bone
27
Fibula
A thin bone distal to the patella
28
Tarsus
The joint and irregular shaped bones located distal to the tibia and fibula
29
Metatarsals
The long thin bones found distal to the Tarsus
30
Cephalic Veins
Veins that runs along the anterior of the forelegs
31
Lateral Saphenous Veins
Small, superficial veins that run diagonally across the lateral surface of the distal part of the tibia.
32
Jugular Veins
Large, superficial veins located on either side of the trachea
33
Femoral Vein
A vein that extends from the groin on the medial aspect of the thigh. Used for blood collection in cats.
34
Saphenous Vein
A vein that extends from the hock (ankle) to the stifle on the medial aspect of the calf. It becomes the femoral vein at the stifle. Used for blood collection in cats.
35
Dorsal Lumbar (Lumbodorsal) Muscle
Located on either side of the midline
36
Triceps
Located caudal to the humerus

39
Semimembranosus/Semitendinosus Muscle Group
The muscle group located in the rear leg, also known as the hamstring muscles
40
Cancellous Bone (Spongy Bone)
Spongy bone that acts as a shock absorber; found near the center of the bone and houses the bone marrow
41
Compact Bone
Highly structured series of bone layers found in the outer portions of the bone; composed of a series of tubelike structured arranged so that the tube shafts are parallel to the bone shaft
42
Haversian Canal
The space through which blood vessels, lymphatic vessels, and nerves travel through compact bone
43
Osteoblasts
Cells responsible for secreting the materials that make up bones
44
Osteocytes
Matured Osteoblasts that make up the majority of mature bones
45
Osteoclasts
Cells that dissolve internal bone material to keep bones lightweight
46
Bone Marrow
The reddish-brown tissue found in the middle of a bone; primarily responsible for producing red blood cells, white blood cells, and platelets, from stem cells
47
Periosteum
A membrane that surrounds the outer surface of a bone, excluding around joints
48
Reticulin
The chief extracellular material in bone marrow
49
Axial Skeleton
The bodies central framework; Includes the bones of the skull, spine, ribs, and sternum
50
Appendicular Skeleton
Supports the axial skeleton; Includes the bones of the legs, shoulders, and pelvis
51
Ligaments
Bands of tough, fibrous connective tissue that connect bones at joints
52
Tendons
Bands that attach muscles to bones
53
Intercostal Space
The space between the ribs
54
Intercostal muscles
The muscles within the intercostal space that connect the ribs and aid the breathing process
55
Paradigit
A digit that does not bear weight (Also called a dewclaw)
56
Anatomy
The study of the structure of living organisms
57
Physiology
The study of body parts and how the preformance of one effects the others
58
Cell
The basic structure of life; come in a wide variety of shapes and sizes and have a variety of functions; all mammalian cells contain a cell membrane, organelles, cytoplasm, and a nucleus.
59
Organs
Composed of groups of tissues that have a common function and work together
60
Tissue
Identical or closely related cells grouped together
61
Mitosis
Cell reproduction by dividing to yield two identical cells
62
Bones
Points of attachment for your muscles, levers for muscle action, mineral storage structures, and sites for production of blood cells
63
Thoracic Limbs
Support the front end of a body during walking
64
Pelvic limbs
Support the rear end of the body during walking
65
Joints
The connection between two bones that help hold bones together and give the skeleton flexibility for movement
66
Diaphragm
The muscle that separates the thorax and abdomen
67
Skeletal Muscle
The most abundant muscle tissue; also called voluntary muscle because it's under voluntary control; appears striped under a microscope
68
Visceral muscle
Involuntary, smooth muscle found in the internal organs such as the urinary bladder and blood vessels
69
Cardiac muscle
Found only in the heart; somewhat striated in appearance but not under voluntary control
70
Neurotransmitters
Chemical substances released at the end of a nerve fiber by the arrival of a nerve impulse which, by diffusing across the synapse or junction, cause the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure
71
Flexor Muscles
Skeletal muscles that flex, or bend, a joint
72
Extensor Muscles
Skeletal muscles that extend, or straighten, a joint
