Skeletal Tissues
The most abundant type of cartilage in the body.
What is Hyaline?
Is part of the integumentary system but not the integument itself.
What is the hypodermis?
The third structural type of joint, alongside fibrous and synovial joints.
What are cartilaginous joints?
The type of muscle cell that lacks sarcomeres.
What are smooth muscle cells?
The most common leukocyte, making up 50-70% of all leukocytes
What are neutrophils?
The defining feature of spongy bone.
What are trabeculae?
This epidermal layer is only found in thick skin, located on the palms and soles.
What is the stratum lucidum/clear layer?
The is functional type of joint allows for free movement.
What are diarthroses?
A specialized functional characteristic of muscles referring to the fact that electrical impulses cause contraction of muscle cells.
What is excitability?
The blood vessel(s) through which deoxygenated blood is carried from the heart to the lungs.
What is the pulmonary arteries/trunk?
Small canals that connect lacunae in compact bone.
What are canaliculi?
The uppermost layer of the epidermis with living cells.
What is the stratum granulosum/granular layer?
The tooth is the only example in the human body of these "peg-in-socket" fibrous joints.
What are Gomphoses?
Ca2+ binds to this molecule which subsequently moves tropomyosin away from actin binding sites.
What is troponin?
Plasma cells produce these "flags" that mark foreign cells for destruction by macrophages.
What are antibodies?
One of the two types of bone formation, alongside endochondral ossification.
What is intramembranous ossification?
The type of sweat glands found in the arm pits.
What are apocrine glands?
These cartilages, located at the ends of opposing bones, are composed of hyaline cartilage and are lubricated by synovial fluid.
What are articular cartilages?
T-tubules are extensions of this.
What is the sarcolemma?
Located on the plasma membranes of foreign cells these molecules induce a lymphocyte response.
What are antigens?
The type of cartilage growth in which chondroblasts in the surrounding perichondrium secrete new cartilaginous matrix.
What is appositional growth?
This layer of the dermis is responsible for flexure lines.
What is the reticular layer?
The synovial joint type in which an egg-shaped surface of one bone articulates with an oval concavity on another bone.
What is condylar/condyloid?
A sheet-like tendon of connective tissue that connects a skeletal muscle organ to a bone.
What is Aponeruosis?
This type of stem cell gives rise to all formed elements but lymphocytes.
What are myeloid stem cells?
