Bones of the skull are separated by immobile joints called sutures

Bones in the skull have many different names but what are the boundaries of each bone? Where they start and stop

Communication

Not a function of the skeletal system

Myofibrils

The contractile units of skeletal muscles are ________.

molecular transport through the membrane

a function of a plasma membrane protein

tactile corpuscles

a skin receptor for touch

organ

a structure that is composed of two or more tissue types that work together to perform specific functions for the body

melanocytes and keratinocytes work together in protecting the skin from UV damage when keratinocytes

accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer

melanin

an inclusion, not an organelle

protection of the brain

best description for the function of the cranial bones

osteoclast

bones are constantly undergoing resorption (breaking bone down) for various reason. These cells accomplishes the process

the temporal bone

bones of the skull you would most associate with hearing and balance

a phospholipids bilayer surrounding the cell

describes the plasma membrane

mitosis

division of the genetic material within the nucleus

excretion of metabolic waste

expiration(breathing out) is how the body removes excessive carbon dioxide from the blood.

to maintain homeostasis

generally the result of the negative feedback process

tissue

group of cells that are similar in structure and perform a common or related function form a(n)

sarcoplasmic reticulum

structure in skeletal muscle cells functions in calcium storage

endomysium

surrounds the individual muscle cell

palms turned posteriorly

the anatomical position is characterized by all of the following except:

osteoblast

the cell responsible for secreting the matrix of the bone

simple squamous

the epithelia forms the walls of the air sacs across which gas exchange occurs in the lungs

a sarcomere

the functional unit of the skeletal muscle is called

the sphenoid is solid like a stone and provides the strength necessary to support the skull

the sphenoid bone is sometimes referred to as a "key stone" of the skull. This is due to the fact that

gross

the study of large body structures, visible to the naked eye, such as the heart

phagocytosis

vesicular transport process occurs primarily in some white blood cells and macrophages
