Anatomical Terminology
2
Anatomical Structures
3
Vocabulary Bone Joint Joint Capsule Ligament Cartilage Meniscus
Dense, calcified connective tissue Bone Where 2 bones meet Joint Saclike structure that encloses the end of bone Joint Capsule Connects bone to bone Ligament Tough elastic shock absorbing tissue that covers ends of bones Cartilage Crescent shaped connective tissue between bones that cushions Meniscus
4
Vocabulary Muscle Tendon Origin Insertion Fascia Bursa Nerve
Tissue made of bundles that contract for movement Muscle Connects muscle to bone Tendon Place muscle begins Origin Place muscle ends/attaches to a bone Insertion Flat layer of fibrous connective tissue that covers groups of muscles Fascia Fluid filled sac that provides cushion between bones & tendons Bursa Helps with feeling (sensory) and movement (motor) Nerve
5
Bone-dense, calcified connective tissue
6
Joint- Where 2 bones meet
7
Joint capsule-saclike structure that encloses the end of bones
8
Ligament-connects bone to bone
9
Cartilage-protects bones from grinding together in a joint; shock absorbers
10
Meniscus- crescent shaped connective tissue between bones that provides cushioning
11
Muscle-tissue that when stimulated contracts and produces movement
12
Tendon-tissue that connects muscle to bone
13
Origin-where a muscle starts at a joint
14
Insertion-where a muscle ends/stops at a joint
15
Fascia- Flat layer of fibrous connective tissue that covers groups of muscles
16
Bursa-a small sac between a muscle and a bone; provides lubrication
17
Nerve-helps with feeling (sensory) and movement (motor)
18
Anatomical Position When a human body is in an upright (standing) position Arms at side Palms forward
19
Division of the body for dissections
Anatomical Planes Division of the body for dissections
20
Types of Anatomical Planes
Sagittal- left and right sides
21
Coronal-Front and back
Types of Anatomical Planes Coronal-Front and back
22
Transverse-top and bottom
Types of Anatomical Planes Transverse-top and bottom
25
Terms of Relationship
26
Superior (cranial)-above, towards the top
27
Inferior (caudal)-below, towards the bottom
28
Anterior (ventral)- towards front
29
Posterior (dorsal)- towards back
30
Medial- closer to midline of body
31
Lateral- farther from midline of body
32
Proximal- closer to top of limb
33
Distal- closer to bottom or end of limb
34
Superficial-close to the surface
35
Deep-deep to the surface
36
External-outer
37
Internal-inner
38
Central-close to the center
39
Peripheral-away from the center/out to the side
40
Parietal-outer
41
Visceral-inner
42
Supine: Lying face upwards
43
Prone: Lying face downwards
44
Knowledge Check Complete Anatomical Terms Worksheet
45
Action-what movement a muscle does
Flexion Extension Abduction Adduction Internal rotation External rotation
46

47
Flexion-to bend or decrease the angle at a joint.
Wrist Shoulder Elbow Hip Knee Flexion can occur at: Shoulder, Elbow, Wrist, Fingers, Trunk, Hip, and Knee, and Toes
48
Extension-to straighten or increase an angle at a joint
Knee Wrist Shoulder Hip Elbow Extension can occur at: Shoulder, Elbow, Wrist, Fingers, Trunk, Hip, and Knee, and Toes
49
Abduction-to take away from the midline or center of the body
Shoulder Hip Abduction can occur at: Shoulder, Hip, Fingers, Toes
50
Adduction-to bring back to or add back to the midline or center of the body
Shoulder Hip Adduction can occur at: Shoulder, Hip, Fingers, Toes
51
Internal rotation-when a bone in the joint rolls or rotates forward in its socket
Shoulder Hip Internal Rotation can occur at: Shoulder, Hip
52
External rotation-when a bone in the joint rolls or rotates back in its socket
Shoulder Hip External Rotation can occur at: Shoulder, Hip
