Definitions of anatomic locations and positions Flashcards
Posterior
Back of the body,dorsal
Anterior
Front of the body, ventral
Superficial
Located close to or on the body surface
Deep
Below the surface
Proximal
Closer to any reference point
Distal
Farther from any reference point
Superior
Toward the head;higher (cephalic)
Inferior
Away from the head;lower (caudal)
Medial
Toward the midline of the body
Lateral
Away from the midline of the body;to the side
ipsilateral
On the same side
Contralateral
On the opposite side
Unilateral
One side
Bilateral
Both sides
Prone
Lying face down
Supine
Lying face up
Vagus
Distal segment of a joint deviates laterally
Varus
Distal segment of a joint deviates medially
Arm
The region from the shoulder to the elbow
Forearm
The region from the elbow to the wrist
Thigh
The region from the hip to the knee
Leg
The region from the knee to the ankle
Kinesiology is?
The study of the mechanics and specifically evaluates muscles, joints,and skeletal structures and their involvement in movement.
What is biomechanics.
The study of the motion and causes of motion of living things using a branch physics known as mechanics.
Kinesiology is based on three fields of science
Biomechanics ,musculoskeletal anatomy and neuromuscular physiology. a
Sagittal plane
Divides into right and left sides
Frontal plane or coronal
Divides in anterior and posterior sides
Transverse or cross sectional,axial, or horizontal
Dived into superior and inferior
Flexion
Movement resulting in decrease of the joint angle.
Extension
Movement resulting in the increase of joint angle.
Internal medial rotation
Rotation in the transverse plane toward the midline
External lateral rotation
Rotation in the transverse plane away from the midline
Three primary anatomical structures of the musculoskeletal system
Bones, joints, muscles.
Rom?
Interaction of the bones joints muscles
How many bones in The body. How many voluntary?
- 177.
Axial skeletal
Skull ,hyboid(jaw) vetrebL column, sternum, and ribs
AppendiculaR
Upper and lower limbs girdles
Diaphysis
Shaft or long part of bone
Epiphysis
Ends of bones covered in cartilage
Cartilage
Resilient semi rigid form of connective tissue that reduces friction and absorbs shock in synovial joints.
Metaphysis
Where the bones connect in a mature none
Compact bones
Arranged in the osteos contains few spaces.
Spongy bone
Trabeculae. Open spaces filled with red bone marrow which produce blood
Ligaments
Tough fibrous connective tissues anchoring bone to bone.
Joints
Articulation between bones.
Synathrodial, amphiarthrodial, diarthrodial
Joint movement is…
Rolling, spinning, sliding of joint surfaces.
Periosteum
A membrane covering the surface of the bone. Serves as a point of attachment for ligaments and tendons and critical for bone growth, repair and nutrition.
Three types of muscle tissue
Skeletal, cardiac and smooth
Agonist
Prime mover of a muscle
Antagonist
Muscles that relax to allow movement
Synergists
Prevent unwanted muscle movements
