BODY TISSUE Flashcards
group of cells with similar structure and function
tissues
what are the 4 primary types of tissues
- epithelium
- connective tissue
- nervous tissue
- muscle tissue
type of tissue found in: body coverings, body linings, glandular tissue
epithelial tissue
a tissue, its main function is: protection, absorption, filtration, secretion
epithelial tissue
tissue found everywhere in the body; the most abundant and widely distributed tissues
main function:
- binds body tissue together
- supports the body
- provides protection
connective tissue
a tissue that produce movement
muscle tissue
what are the three types of muscle tissue
- skeletal muscle
- cardiac muscle
- smooth muscle
a muscle that can be control voluntarily; cell are striated; have more than one nucleus
skeletal muscle
a muscle found only in the heart; pump blood involuntarily; cell striated; one nucleus per cell;
cardiac muscle
an involuntary muscle; surrounds hollow organs; no visible striations; one nucleus per cell; found in the digestive system
smooth muscle
a type of tissue, sends impulses to other areas of the body
irritability
conductivity
nervous tissue
the standard reference position of the body
anatomical position
refers to a person standing upright with the face facing directed forward; upper limbs hanging to the sides, and the palms of hands facing forward
anatomical position
3 major planes of the body
- coronal (frontal)
- mid-sagittal
- transverse or axial plane
oriented vertically, divides the body into anterior and posterior parts and right angle to median plane
coronal/ frontal plane
plane that passes through the center of the body dividing it into equal right and left halves
mid-sagittal plane
divides the body into superior and inferior parts
transverse or axial plane
means below or down
inferior
means above or up
superior
means toward the front of the body
anterior/ ventral
means toward the back of the body
posterior/ dorsal
away from the midline of the body
lateral
toward the midline of the body
medial
closer to the point of attachment/ origin
proximal (near the head)
farther from the point of attachment
distal (near the toes)
toward or on the surface
superficial
away from the surface, internal
deep
is a movement that takes place in the sagittal plane
flexion
means straitening of the joint and usually takes place in the posterior direction
extension
lateral movement of the trunk in the coronal plane
lateral flexion
is a movement of the limb toward the body in the coronal plane
abduction
is the movement of limb toward the body in the coronal plane
adduction
is the term applied to the movement of the part of the around its axis
rotation
is term applied to the movement that result in the anterior surface of the part facing medially
medial rotation
is the term applied to the movement that results in the anterior surface of the part facing laterally
lateral rotation
is a medial rotation of the forearm in such a manner that the palm of the hand faces posteriorly
pronation
is a lateral rotation of the palm up
supination
movement in which one end of an appendage remains stationary while the other end makes circular motion
circumduction
what are the 3 main body cavities in the body
- thoracic cavity
- abdominal cavity
- pelvic cavity
enclosed in the thoracic wall and the diaphragm is subdivided into three major compartments
thoracic cavity
cavity/ies that enclose the lungs
left and right pleural cavity
the one separating the pleural cavities
mediastinum
abdomen and pelvis form single best body cavity; biggest single body cavity
abdominopelvis cavity
opening of the abdomen by the surgeon
laparotomy
refers to the gap or spaces formed inside the skull
intracranial cavity
refers to the gap or spaces formed inside the skull; biggest compartment
intracranial cavity
protect the nervous system; back part of our body
dorsal cavity
cavity in brain
cranial cavity
cavity in spinal cord
spinal cavity
houses the visceral organs (thoracic cavity & abdominopelvic cavity)
vetral cavity
