Parts of a Horse: Names, Functions, and Diagram

Have you ever wondered what each part of a horse is called and what it does? The parts of a horse include the head, neck, back, legs, hooves, and tail. Each part has a specific function that helps the horse move, eat, breathe, sense its surroundings, and maintain balance. Learning horse parts with names and functions helps you build animal vocabulary and understand basic horse anatomy. From the muzzle and mane to the fetlock and hock, these terms make it easier to identify the different parts of a horse.

Parts of a Horse: Names and Functions

The external parts of a horse have different roles in movement, feeding, protection, and communication. The table below lists the main horse parts with short descriptions of their functions.

Horse Part	Location	Function
Head	Front of the body	Contains the brain, eyes, ears, nose, and mouth.
Ears	Top of the head	Detect sounds and turn toward their source.
Forehead	Above the eyes	Forms the front upper area of the head.

Flank	Between the last ribs and hindquarters	Allows movement as the abdomen expands and contracts.
Belly	Underside of the body	Covers and supports the abdominal organs.
Tail	Rear of the body	Helps swat away flies and communicate through movement.
Dock	Base of the tail	Contains the tail vertebrae and muscles that move the tail.
Elbow	Upper front leg, near the body	Helps the forelimb bend and move.
Forearm	Between the elbow and knee	Contains muscles that move the lower front leg.
Knee	Middle joint of the front leg	Allows the front leg to flex and extend.
Cannon Bone	Below the knee or hock	Supports the lower leg and bears weight.
Fetlock	Joint above the hoof	Flexes and absorbs some impact during movement.
Pastern	Between the fetlock and hoof	Helps cushion impact and allows the hoof to move.
Hoof	End of each leg	Protects the foot and supports the horse’s weight.
Stifle	Upper hind leg joint	Helps flex and extend the hind limb.
Hock	Large joint of the hind leg	Helps the hind leg generate forward propulsion.
Gaskin	Between the stifle and hock	Contains muscles that help move the hind leg.
Chestnut	Small, hard growth on the inner leg	A natural callosity with no major role in movement.
Ergot	Small, hard growth behind the fetlock	A small callosity found on many horses.

Note: Horse anatomy terms sometimes refer to a region rather than a single structure. The knee and hock, for example, are complex joints made up of several bones and other tissues.

Parts of a Horse Diagram

When studying a diagram, start with the head and neck, move along the back and belly, and then identify the front legs, hind legs, and hooves. This approach helps you remember the names in their correct positions.

Parts of a Horse’s Head

A horse’s head contains the sensory organs and structures needed for eating, breathing, and communicating. Many head-related terms also appear in riding instructions and veterinary care.

Part	Description	Function
Forehead	Area between and above the eyes	Forms the front of the head.
Eyes	Large eyes on the sides of the head	Provide a wide field of vision.
Ears	Movable structures on top of the head	Detect sounds and show attention or mood.
Cheek	Side of the face	Covers the jaw muscles and nearby structures.
Muzzle	Front part of the nose and mouth	Helps the horse explore, eat, and interact with objects.
Nostrils	Two openings in the nose	Allow air to enter and leave the respiratory system.
Lips	Soft edges of the mouth	Help grasp and select food.
Mouth	Opening at the front of the head	Takes in food and begins digestion.
Teeth	Structures inside the mouth	Cut and grind food.
Jaw	Upper and lower bony structures	Supports the teeth and helps with chewing.
Poll	Area behind the ears	Forms the upper part of the head near the neck joint.
Throatlatch	Area where the head joins the upper neck	Provides space for structures involved in swallowing and breathing.

What Is the Difference Between a Muzzle and a Nose?
The muzzle is the front area of the horse’s face, including the nose and mouth region. The nostrils are the openings that allow the horse to breathe. These terms are related, but they do not mean the same thing.

Parts of a Horse’s Legs and Hooves

A horse’s legs support its weight and help it walk, trot, canter, gallop, jump, and stand. The front and hind legs have different structures, so some anatomical names apply only to particular limbs.

Main Parts of the Front Legs

Shoulder: Connects the forelimb to the body and helps produce movement.
Elbow: Joint between the upper forelimb and forearm.
Forearm: Muscular region between the elbow and knee.
Knee: Complex joint in the front leg, equivalent in position to the human wrist.
Cannon bone: Long bone below the knee.
Fetlock: Joint between the cannon bone and the long pastern bone.
Pastern: Short sloping region between the fetlock and hoof.
Hoof: Hard outer covering that protects the foot.

Main Parts of the Hind Legs

Stifle: Joint in the upper hind leg, broadly comparable in position to the human knee.
Gaskin: Muscular region between the stifle and hock.
Hock: Large hind-leg joint that helps the horse push forward.
Cannon bone: Supports the lower hind leg.
Fetlock: Joint above the hoof that flexes under load.
Pastern: Helps the foot absorb impact.
Hoof: Bears weight and protects the structures inside the foot.

What Are the Parts of a Horse’s Hoof?

The hoof is more than a hard outer shell. It contains several structures that protect the foot and help the horse move comfortably.

Hoof Part	Function
Hoof Wall	Hard outer layer that protects the foot and bears weight.
Sole	Bottom surface that protects the underside of the foot.
Frog	V-shaped structure that helps with traction and shock absorption.
Heel	Rear part of the hoof that contributes to support and cushioning.
Coronary Band	Tissue at the top of the hoof wall where new hoof horn grows.
White Line	Junction between the hoof wall and the sole.
Bars	Inward folds of the hoof wall that help support the heel region.

Hoof health affects a horse’s comfort and movement. Cracks, unusual heat, swelling, or persistent lameness may require assessment by a veterinarian or qualified farrier.

External and Internal Horse Anatomy

External anatomy describes the body parts visible on the outside. Internal anatomy refers to organs and structures inside the body of an horse that support breathing, circulation, digestion, and movement.

Body System	Main Parts	Main Function
Skeletal System	Bones, joints, ligaments	Supports the body and protects internal organs.
Muscular System	Muscles and tendons	Produces movement and maintains posture.
Digestive System	Mouth, esophagus, stomach, intestines	Breaks down food and absorbs nutrients.
Respiratory System	Nostrils, nasal passages, trachea, lungs	Takes in oxygen and removes carbon dioxide.
Circulatory System	Heart, blood, blood vessels	Transports oxygen, nutrients, and waste products.
Nervous System	Brain, spinal cord, nerves	Coordinates movement, sensation, and body functions.
Urinary System	Kidneys, ureters, bladder, urethra	Removes waste products and regulates fluid balance.
Reproductive System	Reproductive organs	Supports reproduction.

The horse’s digestive system has a relatively small stomach and a large hindgut, including the cecum and colon. Microorganisms in the hindgut help break down fibrous plant material such as grass and hay.

How Horse Body Parts Help It Move

A horse’s movement depends on several body parts working together. Bones provide support, muscles generate force, tendons transmit that force, and joints allow the limbs to bend.

Shoulders and forelimbs: Help support the front of the body and control foot placement.
Back and loin: Transfer movement between the front and hindquarters.
Hindquarters: Generate much of the force needed for acceleration and jumping.
Joints: Allow controlled bending and extension.
Hooves: Provide contact with the ground and help support body weight.
Tail and neck: Help with balance and communication, although the legs and trunk perform most of the work involved in locomotion.

A horse’s walk has four beats, its trot has two beats, and its canter has three beats. The gallop is a faster gait with a different sequence of footfalls.

Common Confusions About Horse Parts

Some horse anatomy terms sound similar or refer to nearby areas. Remember these differences when learning the names.

Mane vs. Forelock: The mane grows along the neck, while the forelock hangs between the ears over the forehead.
Croup vs. Rump: The croup refers to the upper hindquarter region; the rump is a broader term for the rear body area.
Fetlock vs. Pastern: The fetlock is a joint, while the pastern is the region between that joint and the hoof.
Knee vs. Hock: The knee is on the front leg; the hock is on the hind leg.
Hoof vs. Foot: The hoof is the hard outer structure covering the horse’s foot, not the entire internal foot.
