Skeletal System
What are the main functions of the skeletal system?
Structural support, protect vital organs, allow movement, storing minerals, and produce blood cells from bone marrow.
What is the primary function of the articular system?
The primary function of the articular system is to facilitate movement and provide stability between bones at joints
What is the musculoskeletal system composed of?
bones, joints, and muscles.
What term is used to describe a structure closer to the midline of the body?
Medial
What type of joint is found between the vertebrae in the spine?
Cartilaginous joints
What are the primary minerals stored in bone tissue?
Calcium and Phosphprus
What is the role of joints in the skeletal system, and what are the three main types of joints?
They facilitate movement and provide flexibility to the skeletal system. The three main types of joints are fibrous joints (immovable joints found in the skull), cartilaginous joints (slightly movable joints found in the spine and ribs), and synovial joints (freely movable joints found in limbs), which include hinge, ball-and-socket, pivot, saddle, condyloid, and gliding joints.
What type of muscle tissue is under voluntary control?
Skeletal muscle tissue
What term describes a structure that is closer to the point of attachment or origin?
Proximal
What term describes the movement of a body part away from the midline of the body?
Abduction
What is the name of the longest bone in the human body?
The femur
Which type of joint allows for little to no movement and is primarily made up of dense fibrous connective tissue?
Fibrous joints
What is the name of the tough band of connective tissue that connects muscle to bone?
Tendons
What directional term indicates movement towards the head or upper part of the body?
Superior
What is the primary muscle responsible for running?
Quadriceps
What is the name of the bone in the upper arm, commonly known as the "funny bone"?
The Humerus
What is the function of synovial fluid in synovial joints?
Synovial fluid lubricates and nourishes the joint, reducing friction and providing shock absorption during movement.
What are the three types of muscle tissue in the human body?
Cardiac, smooth, and skeletal muscle tissues
What term describes movement that decreases the angle between two bones or brings them closer together?
Flexion
Which muscle is responsible for flexing the forearm?
Biceps Brachii
What is the difference between compact bone and spongy bone?
compact= dense and outer layer of the bone, protects and and provides strength to the bone.
Spongy= less dense and inner layer of the bone, provides support while also allowing for the exchange of nutrients and waste products.
Which type of joint allows for multi-directional movement and is often found in the shoulder and hip?
Ball-and-socket
Muscles ______, they never __________
Pull, push
