Cartilage is found in several other areas of the body, such as the nasal septum, external ear, eustachian tube, larynx, trachea, bronchi, and intervertebral disks.

身体许多部位都有软骨,例如鼻中隔、耳郭、耳咽管、喉头、气管、支气管以及椎间板。
One example of a synovial joint is the ball-and-socket joint, which is found at the shoulder and hip.
滑液关节的一种为球窝关节,肩膀和臀部广泛存在。
The ball rotating in the socket allows for a wide range of motion.
因球面在关节窝中旋转,关节运动幅度增加。
Bands of strong connective tissue called ligaments bind bones together at the joint.
人们将带状结缔组织称之为韧带,在关节处将骨骼连接在一起。
Some synovial joints contain a bursa,which is a sac-like structure composed of connective tissue and lined with synovial membrane.
许多滑液关节含有粘液囊,它是一种由结缔组织构成的囊状物质,周边富含大量滑液膜。
They are most commonly found between bones and ligaments or tendons and function to reduce friction.
粘液囊在骨骼、韧带以及跟腱之间广泛存在,起到减少摩擦的作用。
Some common bursa locations are the elbow, knee, and shoulder joints.
普遍存在于肘部、膝盖以及肩膀关节处。
Not all joints are freely moving.
不是所有关节都能够活动自如。
Fibrous joints allow almost no movement since the ends of the bones are joined by thick fibrous tissue, which may even fuse into solid bone.
因骨骼末端富含大量纤维组织,它甚至会融合成坚硬骨骼,所以纤维连结几乎无活动性。
The sutures of the skull are an example of a fibrous joint.
头盖骨骨缝就是纤维连结。

Cartilaginous joints allow for slight movement but hold bones firmly in place by a solid piece of cartilage.

软骨连接可轻微活动,但它是通过一块坚硬的软骨将骨骼连接在一起。
An example of this type of joint is the pubic symphysis, the point at which the left and right pubic bones meet in the front of the lower abdomen.
趾骨联合为软骨连接,左右跖骨在下腹前方相连。
SECTION II MUSCULAR SYSTEM
第二部分 肌肉系统
Muscles are bundles of parallel muscle tissue fibers.
肌肉是一捆平行的肌肉组织纤维。
As these fibers contract, they pull whatever they are attached to closer together.
当纤维收缩,肌肉附着骨骼将相互靠拢。
This may move two bones closer or make an opening narrower.
收缩或使两处骨骼靠拢或形成张口。
A muscle contraction occurs when a message is transmitted from the brain through the nervous system to the muscles.
一旦大脑传递信号,信号将通过神经系统传递给肌肉,肌肉就会发生收缩。
The point at which a nerve contacts a muscle fiber is called the myoneural junction.
神经与肌肉纤维连接点叫作神经肌肉接头。
