Anatomy: Brainstem, CSF and Neurons

Brainstem

• The medulla oblongata is the most inferior part of the brainstem.

Cerebrospinal Fluid (CSF)

• CSF is produced through the filtration of blood by the choroid plexus.
• The meninges cover both the brain and the spinal cord.
• CSF is reabsorbed in the arachnoid villi.
• CSF flows in the subarachnoid space.

Neurons

• The proximal end of a neuron has dendrites.
• The neuron's cell body is also called the soma.

Peripheral Nervous System (PNS)

• The PNS does not include the brain and spinal cord.
• Schwann cells are the glial cells of the PNS that form myelin sheaths.

Ascending Tracts

• Ascending tracts of nervous system fibers carry sensory information from the periphery to the brain.

Sarcomere

• The distance between one z-disc and another z-disc defines one sarcomere.

Connective Tissue

• Perimysium is the connective tissue sheath that covers the fascicles.
• Collagen, reticular, and elastic fibers are protein fibers present in connective tissue.

Anatomy

• Proxmial describes the location of the upper arm to the forearm.
• The dens articulate with the axis.
• The scapula does not articulate with the ribs.
• The Sella turcica is a portion of the sphenoid bone.
• The forearm is inferior to the antecubital region in anatomical position.
• The superior portion of the sternum is the manubrium.
• Lacrimal bones are very small bones forming the medial wall of each orbit.

Cellular Biology

• The stages of interphase are prophase, metaphase, anaphase, and telophase.
• Cholesterol is present in the plasma membrane.
• The site where a motor neuron terminal meets a muscle fiber is called the neuromuscular junction.
• A triad is formed by two terminal cisternae and one t-tubule.
• Lysosomes contain enzymes that break down and digest cellular components

Tissues

• Hyaline cartilage, fibrocartilage, and elastic cartilage are the main types of cartilage tissue.
• Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed.
• Blood is a connective tissue.
• Most epithelial tissues are large sheets of cells that cover the body's surfaces exposed to the outside world as well as lining the outside of organs.
• Muscle tissue types include smooth, cardiac, and skeletal muscle.
• Skeletal muscle tissue is voluntary.
• Observing epithelial cells that are arranged in a single layer looking tall and narrow, with the nucleus close to the basal side of the cell indicates columnar epithelial tissue

Other

• Japanese word "Umami" does not mean "Sour Taste".
• A muscle with a similar action that assists the prime mover is a synergist.
• The thoracic cavity houses the pleural, pericardial, and peritoneal cavities.

Bone

• The structural unit of compact bone is the osteon.
• Osteocytes are found in lacunae.
• The term popliteus does not refer to the posterior area of the elbow joint.

Membrane Proteins

• Glycoproteins, channel proteins, and receptors are examples of membrane proteins.

Scapula Classification

• The scapula is classified as a flat bone

Epithelia

• High vascularity is not a structural or functional feature of epithelia.
• Goblet cells are be found in columnar epithelium.

Ribs

• Ribs 11 and 12 are not true ribs because they have no anterior attachments.

Mitosis

• Anaphase is the stage of mitosis when sister chromatids are separated, forming individual chromosomes.

Osteoclasts

• Osteoporosis is a disease characterized by a decrease in bone mass

Muscle

• A group of muscle fibers bundled as a unit is called a fascicle.
• Hair is primarily made of dead, keratinized cells

Anatomical Position

• Upper limbs held out to each side is not part of the anatomical position
• The site where a motor neurons terminal meets the muscle fiber is called the neuromuscular junction.
• The sternum is formed by three parts: the manubrium, the sternal angle and the xyphoid process

Glial Cells

• Microglial cells are all glial cells of the PNS

Anatomy / Long Bone

• Of the following, epiphyseal plate would not be found in a long bone of your anatomy professor

Anatomy / Vertebrae

• The spinous process of C1 vertebrae projects posteriorly

Anatomy / Planes

• The frontal plane is the plane that divides the body or an organ into an anterior and posterior portion.

Anatomy / Superior

• The term superior describes a position or higher than another part of the body

Anatomy / Tibia

• The tibia is the lateral leg bone

Anatomy / DNA

-The four DNA bases are adenine, guanine, cytosine and uracil

Nerve Cells

• After the nerves cells relay information of Distension /Stimulus after you eat lunch to Sensors

Cartilage

• Hyaline cartilage is the most common type of cartilage.

Anatomy / Sella Turcica

• The Sella turcica is part of the Sphenoid bone.

Joint Classification

• Joint classification based on movement is not called classified to the structural

Body Function

• Skeletal muscles rarely relax completely

Movement

• Eversion is not a movement that involves the hands

Mechanical Protection

• The stratum corneum does provide a mechanical protection to the underlying layer
