SKELTAL SYSTEM

Untitled Slide

THE SKULL

• The brain is located within the cranium
• The brain is attached to the spinal cord through a large hole,the foramen magnum

THE NECK

• The vertebral column/backbone is the main axis of the skeleton and it protects the spinal cord
• The spinal cord is located in a neural canal formed by a long series of neural arches
• The neural arch of each vertebra is supported on the body or centrum of the vertebra
• In types of vertebrae,the neural arch extends as a prominent spine thats called a dorsal or a neural
• Where movement between vertebrae is possible, the centra are separated by cartilaginous intervertebral discs.

THE NECK

• The neck is mobile and the cervical vertebrae have a series of interlocking articular and tranverse processes
• This is to limit excessive bending of the neck to protect the spinal cord.
• the atlas articulates with the skull and forms a joint that enables the animal to nod its head up and down.
• Rotation or twisting of the head occurs from the joint between the atlas and the next cervical vertebra,the axis.
• The ligamentum nuchae is a very strong elastic ligament in the dorsal midline of the neck

LOIN, SIRLOIN AND RUMP

• the lumbar vertebrae act like a suspension bridge to support the weight of the abdomen
• The pelvis is formed by three bones on each side
• The most anterior bone on all sides is the ilium
• The most posterior on all sides is the ischium

DEFINITIONS

• Bone-hard tissue, mostly calcium, supports and makes red blood cells
• Cartilage-hard tissue found at the end of long bones to prevent grinding
• Ligament-Strong, white bands of tissue that connect bones at joints
• Marrow-Soft tissue filling the spongy interiors of bones
• Tendon-White bands that connect muscles to bones.

SKELETON

• Framework of hard tissue
• Gives support
• Protects soft tissue
• Serves as Levers in movement

BONE STRUCTURE

• Compact
• Contains vessels,Nerves and Marrow
• Can repair itself
• Organic material gives elasticity
• Inorganic matter gives rigidity

AXIAL SKELETON (SKULL)

• Nasal cavity
• Mandible
• Sinuses
• Temporal bone
• Turbinates

APPENDICULAR SKELETON

• Eating
• Defense
• Connected to axial skeleton by muscles/joints

FORELEG CONTAINS

• Scapula- shoulder blade
• Humerus
• Radius and Ulna

HIND LEG

• Femur- thigh bone
• Tibia and Fibula
• Metatarsus
• Phalages
• Sesamoids
