Tissues & Joints Flashcards
What are the components of connective tissue?
Cells & extracellular matrix
“Connective tissue is the most abundant and diverse animal tissue, providing structure, support, and protection throughout the body. It’s made up of cells, fibers, and a gel-like substance called ground substance”
What are the categories for connective tissue proper?
Loose connective tissue & dense connective tissue (irregular and regular)
What are the categories for specialized connective tissue?
Cartilage & bone
“Specialized connective tissues are a diverse group of tissues that have unique properties and functions, distinct from the general connective tissue. They provide structural support, protection, and facilitate various physiological processes”
The majority of loose connective tissue is ?
Fascia
How are fibers oriented in dense irregular connective tissue?
Fibers are oriented in different directions
Does dense irregular connective tissue resist multidirectional tensile forces or unidirectional tensile forces?
Multidirectional
What are examples of dense irregular connective tissue ? (3)
Joint capsules, skin, & periosteum
“Dense irregular connective tissue, characterized by irregularly arranged collagen fibers, is found in areas requiring strength in multiple directions, including the dermis of the skin, organ capsules, and the submucosa of the digestive tract”
A fibrous connective tissue which attaches muscle to bone
Tendon
A fibrous connective tissue which attaches bone to bone
Ligament
How are the fibers oriented in dense regular connective tissue?
Primarily in one direction
Does dense regular connective tissue resist multidirectional tensile forces or unidirectional tensile forces?
Unidirectional tensile forces
What are examples of dense regular connective tissue? (3)
Tendons, ligaments, & aponeurosis
“An aponeurosis is a thin sheath of connective tissue that helps connect your muscles to your bones. Aponeuroses are similar to tendons”
A flexible connective tissue that keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact
Cartilage
____ cartilage covers the ends of bones wherever there is a joint.
Hyaline
“Hyaline cartilage is a type of connective tissue that forms a smooth, flexible surface on the ends of bones in joints. It is the most common type of cartilage in the body”
What are the two different types of bone?
Cancellous (trabecular & spongy)
Cortical (compact)
“Cancellous bone, also known as spongy or trabecular bone, is a porous, lighter bone tissue found within the inner part of bones, particularly at the ends of long bones and in the spine, characterized by a network of struts called trabeculae.”
“Compact bone, also known as cortical bone, is the dense, hard outer layer of bones that provides strength and protection. It makes up 80% of the human skeleton’s weight and is found in the long bones of the arms and legs. “
The part of the body where two or more bones meet to allow movement.
Joint
Which joint has irregular bony surfaces, small amount of interconnecting fibrous tissue, and allows for virtually no motion ?
Fibrous
“Fibrous joints, also known as synarthrodial joints, are fixed joints where bones are connected by collagen-rich fibrous tissue. They provide strength and stability to body regions, protect internal organs, and aid in weight bearing”
What joint can be found in the skull sutures?
Fibrous joints
Which joint has smooth surfaces separated by a fibrous and gel like material space, and allows for rocking motion?
Cartilaginous
“Cartilaginous joints are a type of joint that connect bones using cartilage. They are characterized by their limited mobility and the presence of a cartilaginous disc or plate between the articulating bones”
Which joint is found in the intervertebral discs of the spine and the pubic symphysis of the pelvis?
Cartilaginous
Which joint has smooth articular cartilage surfaces?
Synovial
“A synovial joint, also known as a diarthrosis joint, is a type of movable joint that allows for smooth and flexible movement between two or more bones.”
Which joint makes up the majority of joints in our body like the shoulder and hip?
Synovial
What is the unique feature of synovial joints?
They have a joint capsule
The outer fibrous layer of a joint capsule has a _____ role and the inner fibrous layer of a joint capsule has a _____ role
Mechanical; nourishment
What kind of tissue is thoracolumbar fascia?
Dense regular because it is an aponeurosis
