Study Notes

Axial Skeleton

Consists of the external bones of the cranium
The spinal cord exits the skull through the foramen magnum
The joint that connects the head with the neck is the atlanto-occipital joint

Middle Ear Bones

The three tiny but important pairs of bones are known collectively as the ossicles
Ossicles are hidden inside the middle ear
The ossicles consist of the malleus, incus, and stapes

Skull

The bony labyrinth is a thin layer of bone at the base of the middle ear
It houses the middle and inner ear
The anatomy of the bony labyrinth is different between humans and other animals
The bony labyrinth surrounds the tympanic cavity and can become infected

Hyoid Bone

The hyoid bone supports the tongue, larynx, and trachea
It helps the animal swallow
The hyoid bone is usually referred to as a single bone, but it is composed of several individual portions united by cartilage

Spinal Column

Also known as the vertebral column
Made up of 33 vertebrae
The sections of the spinal column are:
- Cervical vertebrae (7)
- Thoracic vertebrae (12)
- Lumbar vertebrae (5)
- Sacral vertebrae (5)
- Coccygeal vertebrae (4)
The arch of the vertebrae houses the spinal cord
Vertebrae characteristics are:
- Processes are sites for muscle attachment and provide leverage for movement
- The single, spinous projecting dorsal process and the two transverse processes vary in size among vertebrae

Sacral Vertebrae

Forms a pelvis on each side called the sacroiliac joint
Sacral vertebrae are unique in that they fuse to form a single solid structure called the sacrum

Appendicular Skeleton

The bones of the appendicular skeleton are numbered instead of named, starting at the medial side and working laterally
Each digit is made up of 2-3 bones called phalanges
The individual bones that make up the digits are metacarpals, metatarsals, and phalanges
Cats and dogs have another type of bone within their paws besides phalanges, carpals, and metacarpals
The calcaneal tuberosity of the fibular tarsal bone projects upward and backward to form the point of the hock

Fibula and Patella

The fibula is a bone in the lower leg
The patella is a small bone at the front of the knee joint
