Skeletal system
*Provides internal framework that supports the body
*Protects internal organs and helps fight disease by producing white blood cells
*Makes movement possible by working in concert with muscle contraction and relaxation
*Stores calcium, a vital resource
*Forms blood cells—process is called
hematopoiesis
What are functions of the Skeletal System
The shaft of the long bone
What is diaphysis
The thin connective tissue lining the medullary cavity of the long bone
What is Endosteum
Connective tissue surrounding an individual muscle fiber
What is Endomysium
Structure of bone responsible for producing blood cells.
What is Red bone marrow
Divisions of Skeleton containing the-
* Skull
* Spine, or vertebral column
*Thorax (includes ribs)
What are the Components of the Axial Skeleton
Connects bone to bone
What is ligaments
The outer layer of the bone containing blood vessels, nerves and osteogenic cells
What is Periosteum
Functional unit of a skeletal muscle fiber
What is a Sarcomere
Muscle primary responsible for flexion of the forearm at the elbow
What is the Biceps brachii.
Division of skeleton containing
*Upper extremities, including shoulder (pectoral)
girdle and
*Lower extremities, including hip (pelvic) girdle
What is the The appendicular skeleton
Muscle located in the shoulder, responsible for arm movement and giving the shoulder named for its shape.
What is the deltoid muscle
Type of joint allows the greatest range of motion (ROM)
What is Hinge Joint
Muscle tissue that is striated and involuntary
What is is Cardiac muscle tissue
Muscle responsible for head rotation and neck flexion
What is the Sternocleidomastoid
Lines joint capsule and secretes lubricating fluid
What is Synovial membrane
Muscle in the human body, primarily responsible for extending and stabilizing the hip, supporting upright posture, and generating forceful lower-body movements named based in its large size
What is gluteus maximus
Structure of bone allows lengthwise bone growth
What is the role of the epiphyseal (growth) plate.
Largest muscle of the quadriceps group and extends the leg at the knee
What is Rectus femoris
Contraction where muscles contract without causing movement
What is Isometric contractions
Composed of:
• 12 pairs of ribs
• Sternum or breastbone
• Thoracic vertebrae
What is the Thorax
Muscle tissue that is nonstriated and involuntary
What is smooth muscle or visceral muscle
Bone cell responsible for breaking down bone tissue (resorption
What is Osteoclast
Muscle tissue that is striated and voluntary muscle
What is Skeletal Muscle Tissue
Movement that decreases the angle between two bones at a joint
What is flexion
