Osseous Tissue
These bones have complex shapes and don't fit into the other bone categories, often providing support or protection. Examples include vertebrae, sphenoid, calcaneus, and ethmoid.
What are irregular bones?
These are located in the stratum basale, these specialized epidermal cells are responsible for detecting light or crude touch sensations.
What are Merkel Cells?
These glands secrete their products onto body surfaces or into body cavities, including internal lumens, unlike endocrine glands which secrete directly into the bloodstream.
What are exocrine glands?
This condition occurs when uric acid crystals accumulate in the joints, leading to intense pain, swelling, and inflammation, often affecting the big toe.
What is Gout?
This structure, shaped like a cone, marks the end of the spinal cord and is located near the level of the first or second lumbar vertebra.
What is the Conus Medullaris?
These bones are formed directly from mesenchymal tissue through a process that doesn't involve cartilage, and include the clavicle, mandible, and the flat bones of the skull.
What are bones formed by intramembranous ossification?
Blistering, intense pain, and damage extending beyond the superficial layer into connective tissue and capillaries are characteristic of burns affecting these two specific skin layers.
What are the epidermis and dermis?
This type of epithelium features multiple layers, with cuboidal cells near the base and flat cells at the surface.
What is stratified squamous epithelium?
This movement, commonly performed by ballet dancers, involves pointing the toes downward and increasing the angle between the foot and the lower leg at the ankle joint.
What is Dorsiflexion?
This delicate layer of the spinal meninges clings tightly to the surface of the spinal cord and contains blood vessels that nourish nervous tissue.
What is the Pia Mater?
These tiny channels in bone tissue allow the exchange of nutrients and waste between osteocytes, even within the hard, calcified matrix.
What are Canaliculi?
These sweat glands become active during emotional stress and secrete a thicker sweat that can contribute to body odor.
What are Sudoriferous Apocrine glands?
This type of flexible connective tissue connects the anterior extremity of a rib to the sternum, providing flexibility and support.
What is Hyaline Cartilage?
This fluid-filled sac acts as a cushion between bones and tendons or muscles, reducing friction and preventing wear and tear in areas like the shoulder, knee, and elbow.
What is a Bursa?
These white matter tracts in the spinal cord carry sensory information toward the brain and are responsible for functions like touch, temperature, and pain sensation.
What are Ascending Sensory Tract?
This rare genetic disorder is characterized by ectopic calcification of soft tissues, progressive immobility, and pain, with symptoms varying based on the location of abnormal bone growth.
What is Fibrodysplasia Ossificans Progressiva (FOP)
This layer of the epidermis provides waterproofing, forms calluses, and serves as the skin’s primary barrier of protection.
What is Stratum Corneum?
These cells are responsible for maintaining the matrix of cartilage by producing and maintaining the extracellular matrix, and they are typically found within lacunae
What are Chondrocytes?
These joints are connected by dense connective tissue, and examples include the joint between a tooth and the jaw as well as the sutures in the skul
What are Fibrous Joints?
This network of nerves, formed by the anterior rami of C1 to C4, gives rise to the phrenic nerve, which is responsible for motor control of the diaphragm.
What is the Cervical Plexus?
This is where the secondary ossification center forms during endochondral bone development in a long bone.
What is the epiphysis?
This layer of the epidermis is only found in thick skin, such as the palms and soles, and provides an extra layer of protection.
What is the stratum lucidum?
This tissue, found in areas like the intervertebral discs, combines collagen fibers with a gel-like matrix for tensile strength and shock absorption.
What is Fibrocartilage?
These classifications of joints are determined by their range of motion, with one type allowing no movement, another permitting limited movement, and the third allowing a full range of motion
What are synarthrosis, amphiarthrosis, and diarthrosis?
These four branches, which include pathways to deep muscles, internal structures, and autonomic ganglia, emerge from spinal nerves shortly after they exit the spinal cord.
What are the posterior (dorsal) rami, anterior (ventral) rami, meningeal branch, and rami communicantes?
