69
Cartilage
Flexible and firm type of specialized connective tissue.
| there are three types: Hyaline cartilage, fibrocartilage, yellow cartilage.
70
Hyaline cartilage

72
Yellow cartilage
Firm and the elastic. Found in pinna which is the flexible part of your ear, nose, epiglottis.
73
Bone
Specialized connective tissue. There are 206 bones in human body. two types: compact which is dense and gives bone it's
White appearance. And spongy or cancellous bone that is more porous; usually found at the end of bones also contains white and red blood cell Plasma matrix
74
Compact bone
Dense. Gives bone white appearance
75
Sponji/cancellous bone
Molitoris; usually found at the end of bones.
76
Blood
Plasma is the food component of blood this is considered a connective tissue. Red and white blood cells are suspended in matrix.
77
Muscle tissue
There are three different types: striated, smooth, cardiac.
78
Striated tissue
Muscle tissue that is also called skeletal muscle. Has striped appearance and is classified as voluntary or somatic muscle that moves in response to conscious, voluntary movement.
79
Smooth muscle
Found in digestive tract and blood vessels automatic and involuntary
80
Cardiac muscle
Only found in heart. Involuntary.
81
Nervous tissue
Specialized tissue that allows for communication throughout the body
82
Neurons
Also called nerve cells. They transmit information from neuron to neuron or to other places throughout the body
83
Tissue aggregates
Tissues that combine to form larger structures. These include: fascia, tendons, ligaments, bones, joints, muscles.
84
Fascia
Connective tissue that surrounds muscles, groups of muscles, organs, blood vessels or nerves.
85
Tendons
Tough, nonelastic cords. Attach muscles to bones, muscles to cartilage or muscle to muscle. Subtype of tendons is aponeurosis. Aponeurosis is broadsheets of tendinous expansion serving as a covering for muscle
86
Aponeurosis
Broadsheets of tendinous expansion serving as a covering for muscle. A subcategory of tendons.
87
Ligaments
elastic fibers with limited elasticity. Join bone to bone, going to cartilage, and cartilage to cartilage.
88
Bones
Provide skeleton that supports and protects organs and tissues. When bones join together, it is called articulation. There are 206 bones of the human body. Bones can be characterized by length or shape: long, short, flat, a regular and accessory.
89
Joints
Connection between bones or cartilage. Classified based on degree of movement. Diarthrodial is high mobility, amphiarthriodial is limited ability, and synarthrodial is no mobility.
90
Diarthrodial joint
A joint that has high mobility. Also known as synovial joints because synovial fluid found in joint space.
There are seven different types of diarthrodial joints: Plane or gliding joints, sepheriod, condylar, trochoid, sellar, ellipsoid, hinge.
91
Amphiarthrodial joint
A joint that has limited mobility. Also known as cartilaginous joints. There are two types synchondrosis and symphysis.
92
Synarthrodial joint
A joint that has no mobility. Also known as fibrous joints. There are two types syndesmosis and sutures.
93

104
Gomphosis joint
A type of suture with no mobility. It is a joint found between the alveolus or tooth socket and the tooth
105
Muscles
Muscles can be long or short. All have an origin and insertion. Origin is the least mobile point of attachment. Insertion is the point of attachment that moves when a muscle is contracted. Muscles may be agonists, antagonistic, or synergistic nature when movement occurs. All muscles are innervated by a single nerve.
106
Origin of muscle
The least mobile point of attachment
107
Insertion of muscle
The point of attachment that moves when a muscle is contracted
