Hands and Feet; Foot Bones and Their Anatomy
The human foot is a strong, weight-bearing structure that consists of 26 bones, 33 joints, and more than 100 muscles, tendons, and ligaments. The bones in the foot are arranged in two groups: the proximal group and the distal group.
The proximal group, which includes the ankle and heel bones, is responsible for weight distribution and movement. The distal group, which includes the toes, is responsible for movement and sensation.
The foot is divided into three sections: the hindfoot, the midfoot, and the forefoot. The hindfoot is composed of the ankle bone and the heel bone. The ankle bone articulates with the two lower leg bones (the tibia and fibula), and the heel bone is attached to the Achilles tendon. The midfoot is composed of the navicular, cuboid, and three cuneiform bones. The navicular bone articulates with the ankle bone, and the other two bones articulate with the metatarsals. The forefoot is composed of the five metatarsals and the five proximal phalanges.
The foot is a complex structure that performs a variety of functions, including weight distribution, movement, and sensation. The bones in the foot are arranged in a way that allows the foot to adapt to different surfaces and perform a variety of movements. The bones in the hindfoot are responsible for weight distribution, and the bones in the forefoot are responsible for movement.
Structure of the Hands
The hands are a complex structure of bones, muscles, tendons and ligaments. The hands are made up of 27 bones, which includes the five metacarpal bones in the palm of the hand, and the 14 phalanges bones in the fingers. The muscles in the hand are responsible for the movements of the fingers and thumb, and the tendons and ligaments connect the muscles to the bones. The hands are extremely flexible and versatile, allowing us to perform a wide range of tasks.
Areas of the Hand
There are many areas of the hand that are used for different purposes. The palm is the bottom side of the hand and is used for gripping and holding objects. The fingers are used for gripping, picking up objects, and typing. The thumb is used for gripping, grabbing, and picking up objects. The back of the hand is used for scratching and slapping. The knuckles are used for punching.
Anatomy of the Skeleton Hand Bones
The skeleton hand bones are made up of the carpals, metacarpals, and phalanges. There are eight carpals in the skeleton hand, which are the small bones that make up the wrist. The metacarpals are the five bones that make up the hand, and the phalanges are the 14 bones that make up the fingers.
Skeleton Feet
Skeleton feet are the feet of a skeleton. They are the bones of the foot, and they are attached to the leg bones.
Human Skeleton Foot Bones
There are 26 bones in the human foot, which are divided into three groups: the tarsal bones, the metatarsal bones, and the phalangeal bones.
The tarsal bones are the seven bones at the back of the foot. They are: the calcaneus (heel bone), the talus, the navicular, the three cuneiform bones, and the cuboid.
The metatarsal bones are the five bones in the middle of the foot. They are: the first metatarsal bone, the second metatarsal bone, the third metatarsal bone, the fourth metatarsal bone, and the fifth metatarsal bone.
The phalangeal bones are the 14 bones in the front of the foot. They are: the four phalangeal bones of the big toe, the five phalangeal bones of the other toes, and the three phalangeal bones of the heel.
Tarsal Bones
The bones of the ankle and foot are called the tarsal bones. There are seven tarsal bones in the foot. The tarsal bones are:
The calcaneus, or heel bone
The talus, which forms the ankle joint
The cuboid, which is at the outer edge of the foot
The navicular, which is in the middle of the foot
The three cuneiform bones, which are next to the navicular
The five metatarsal bones, which are in the foot’s arch
The five phalanges bones, which are in the toes
Metatarsal Bones
There are five metatarsal bones in each foot. The metatarsals are the long bones that run from the ankle to the toes. They are numbered one through five, starting with the big toe.
The metatarsals are responsible for transferring weight from the heel to the toes. They are also responsible for the movement of the toes.
Phalanges
:
The phalanges are the bones of the fingers and toes. There are two phalanges in the thumb and each finger has three. The big toe has two.
