BONES IN THE BODY Flashcards
internal framework that provides structure, support, and protection to the body.
HUMAN SKELETON
the central axis of the human skeleton. It’s like the core of the body.
AXIAL SKELETON
the bony structure that forms the head. It’s composed of 22 bones, most of which are fused together.
SKULL
Skull composed of how many bones?
22 bones
The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. Facial bones provide cavities for the sense organs (eyes, mouth, and nose), and serve as attachment points for facial muscles.
FACIAL BONE
that forms the cheek bones of the face and articulates with the frontal, sphenoid, temporal and maxilla bones.
Zygomatic
FACIAL BONE
the smallest bones of the face.
Lacrimal
FACIAL BONE
two slender bones that are located at the bridge of the nose.
Nasal
FACIAL BONE
comprises part of the upper jaw and hard palate.
Maxilla
FACIAL BONE
articulates with the base of the cranium at the temporomandibular joint (TMJ).
Mandible (jaw)
Mandible (jaw) articulates with the base of the cranium at the
temporomandibular joint (TMJ)
lies below the mandible in the front of the neck. It acts as a movable base for the tongue and is connected to muscles of the jaw, larynx, and tongue.
HYOID BONE
Also known as spinal column, surrounds and protects the spinal cord, supports the head, and acts as an attachment point for ribs and muscles of the back and neck. It consists of 26 bones: the 24 vertebrae, the sacrum, and the cоссух.
VERTEBRAL COLUMN
Vertebral column consists of:
26 bones
24 vertebrae
the sacrum
the cоссух
Also known as the rib cage, consists of the ribs, sternum, thoracic vertebrae, and costal cartilages. The thoracic cage encloses and protects the organs of the thoracic cavity including the heart and lungs.
THORACIC CAGE
THORACIC CAGE OR RIB CAGE consists of ?
Ribs
Sternum
Thoracic vertebrae
Costal cartilages
It also provides support for the shoulder girdles and upper limbs and serves as the attachment point for the diaphragm, muscles of the back, chest, neck, and shoulders.
Thoracic cage / Rib cage
Composed of the bones of the upper and lower limbs.
It also includes the pectoral, or shoulder girdle, which attaches the upper limbs to the body, and the pelvic girdle, which attaches the lower limbs to the body.
APPENDICULAR SKELETON
Transfer force generated by muscles acting on the upper limb to the thorax.
PECTORAL GIRDLE
Pectoral Girdle composed of 2 bones
Clavicles (Collarbones) in the interior
Scapula (Shoulder blades) in the posterior
The upper limb contains bones of the:
Arm (shoulder to elbow)
Forearm
Hand
extends from the shoulder to the elbow and contains the humerus.
ARM
the longest and largest bone of the upper limb. It forms a joint with the shoulder and with the forearm at the elbow.
HUMERUS
extends from the elbow to the wrist and consists of two bones.
FOREARM
